This commit allows F-Droid to hide itself from the laucher.
It can be hidden either as response to a panic trigger
or as a manual action by long pressing the floating search button.
The latter needs to be explicitly enabled in the settings.
Once hidden, a semi-functional fake calculator app appears in the
launcher that can be used to bring F-Droid back by entering a
pre-defined PIN.
According to the following this is not supported:

Fixes#979.
* Replace hardcoded color values with references to style.xml,
which in turn has different values for light and dark theme.
* Force reload the activity to get the theme applied.
TODO:
* Swap uses it's own theme, need to figure out a way to
handle that. Currently the main Nearby screen which you get
to from the bottom navigation is ok, but anything after
that is light / custom themed.
