- Move client storage to the Node-RED user directory.

Browse Source 
- Remove mention of Device ID being required for encryption (since it can now auto generate if not provided this could make people think they have to set it when that isn't the case)
- matrix-js-sdk updated from ^v15.3.0 to ^v15.5.0
- got updated from ^11.8.2 to ^12.0.1 (this also required us to change how we import this library in code)
- Node-RED version requirement added for >=v1.3.0
- NodeJS version requirement added for >=v14.0.0
- removed `process` dependency
- send-image node fixed so error doesn't get thrown (`matrix-js-sdk` updated causing some errors)
- updated send-image node docs to explain that msg.contentType is necessary for some clients to render the image (otherwise it could display as a blank message in the room).
- If a matrix server configuration node was missing it's User ID it would throw a TypeError instead of telling the user the actual issue.
- Updated user list example: it now paginates all users on the server (if you had a lot of users the message would fail to send because it was too large)
- Added example for creating a room and inviting a user
- Added example for joining a mentioned room
- Added example for listing out a user's or server's rooms
- Added example for getting session data from a user via whois info
- Added example for getting a room's user list
- Added example for downloading & storing received files/images
- Added example for kicking/banning user from a room.
- Added example for deactivating a user
- Removed message in the room-users config stating it only works if you are an admin
- Receive node now outputs `msg.filename` for files and images

When someone sends the text "users" they get a HTML message back containing all the current users on the server.
When someone sends the text "users" they get a HTML message back containing all the current users on the server. If your server has a lot of users this paginates and sends a message with 25 users per message.
This requires admin privileges.

### Respond to "newroom" by creating new room and inviting user
[View JSON](respond-users-list.json)
When someone sends "newroom" a new room will be created and the user that said the message will be invited. The client will also send a welcome message into the new room.
![respond-newroom-invite.png](respond-newroom-invite.png)
### Respond to "joinroom <room_id_or_alias>" by joining mentioned room
[View JSON](respond-joinroom.json)
When someone sends "newroom" a new room will be created and the user that said the message will be invited. The client will also send a welcome message into the new room.

### Respond to "rooms <user_id>" with user's rooms (list server's rooms if <user_id> is left blank)
[View JSON](respond-rooms.json)
Responds to "rooms <user_id>" with that user's rooms. If the message is just "rooms" it responds with a list of all rooms the server is participating in.
Note: If there are a lot of rooms this may fail to send the message as it is too large. This also only works for user's that are on the current server.
This requires admin privileges.
![respond-rooms.png](respond-rooms.png)
### Respond to "whois <user_id>" with information about the user's session
[View JSON](respond-whois.json)
This lists out the user's session info. Each session contains the IP address, when it was last seen, and the user agent. Useful to find out more about a specific user on your server.
Note: If there are a lot of sessions this may fail to send the message as it is too large. This also only works for user's that are on the current server.
This requires admin privileges.
![respond-whois.png](respond-whois.png)
### Respond to "room_users" with current room's users
[View JSON](respond-room-users.json)
List out the users participating in a room.
Note: If there are a lot of users in the room this will fail to send due to a large message error.
![respond-room-users.png](respond-room-users.png)
### Download & store all received files/images
[View JSON](store-received-files.json)
Download received files/images. If the file is encrypted it will decrypt it for you. The decrypt node downloads the file for you otherwise you need to use a HTTP Request node to download the file.
Note: You may need to edit the storage directory for this to work. Default action is to create a `downloads` folder in the Node-RED directory and places files in that but there is a good chance your Node-RED instance doesn't have access to write to this directory.
![store-received-files.png](store-received-files.png)
### Kick/Ban user from room
[View JSON](room-kick-ban.json)
If you say "kick @test:example.com" the bot will kick @test:example.com from the current room.
If you say "ban @test:example.com" the bot will ban @test:example.com from the current room.
Note: This requires the bot to have permissions to kick/ban in the current room.
![room-kick-ban.png](room-kick-ban.png)
### Deactivate user
[View JSON](deactivate-user.json)
If you say "deactivate_user @test:example.com" the bot will deactivate the @test:example.com account on the server.
Note: This requires the bot to be a server admin.
WARNING: Accounts that are deleted cannot be restored. If you want to temp-disable edit the user instead.
