Update these to the current mockups. Since there is now the extended
layout for terminals in the OSK, the downwards looking arrow we used for
the "hide OSK" action is visually too similar to the "cursor down" key
nearby.

quickSettings: Fix slider accessibility
Since we put the actual slider into a bin to get a proper focus
indication, the slider isn't focused anymore and its accessible object
is therefore invisible to the screen reader.
Fix this by passing the slider's accessible object to the actor
that takes the focus.
This prevents _sync() being called after actor destruction (since actor
destruction became more reliable in mutter@3d94c7cc2) and so eliminates
this shutdown error:
```

This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.
