Move all Etherpad's access control from Meteor to a separated [Node application](https://github.com/bigbluebutton/bbb-pads).
This new app uses [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
to create groups and manage session tokens for users to access them. Each group
represents one distinct pad at the html5 client.
- Removed locked users' access to pads: replaced readOnly pad's access with a new pad's content sharing routine
- Pad's access is now controlled by [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
- Closed captions edited content now reflects at it's live feedback
- Improved closed caption's dictation mode live feedback
- Moved all Etherpad's API control from Meteor to a separated [app](https://github.com/bigbluebutton/bbb-pads)
- Included access control both in akka-apps and bbb-pads
This complements #12694, which was initially made using an
existent font (which may vary it's size depending on OS/browser)
Added a new specific icon for the device icon selector
Thanks to @ramonlsouza who found this problem
This commit adds a new small button over the "Phone/audio" button. Currently
this button pops up the device audio selector, which contains the "Leave audio"
option. This commit brings back the "Leave audio" behavior to the phone
button, using a new smaller button to switch between audio devices.
This issue address the problem reported by #12320 and complements the work done
for #9723.
Some technical details:
Added a new component : ButtonEmoji. This allow us to add an emoji inside
another button.
Modified dropdown trigger a bit: if the trigger contains a ButtonEmoji,
then we will use the emoji to trigger the dropdown (instead of the button
itself). This commit doens't change the default behavior of dropdown (when
the trigger doesn't have a ButtonEmoji component), to avoid regressions with
current dropdowns; this will only change it's behavior when used with
the new ButtonEmoji component.
