This updates the custom status context menu to match the latest comps. A single
button is used for setting / clearing, depending on what is appropriate.
The state logic is also changed to depend on events and storage from js-sdk for
the committed status message. This makes it easy to distinguish the value being
edited from what's currently committed.
Text colour ended up being the link colour on images because the
whole image is in an `a`, but stickers are not so it got the default
font colour, which might be black. Define an explicit colour.
Also set pointer-events: none so you can hover over the gif icon
too (I managed to make the message panel small which made the icon
cover most the image, so this prevented the gif from animating
at all).

There are various versions of Nunito in circulation, and some have errors in
their metrics or smaller supported character sets. To ensure all users get the
expected experience, don't allow local copies of Nunito to be used.

text inputs are now styled at every occurence in the app,
style input by default, and provide a .mx_textinput class
if buttons need to appear inside the input styling.
Before this was partially done in _common.scss, but as it's
highly theme-dependent, makes more sense to do it in the theme.
