GtkApplication by default appends "icons" to the app id and add that
to the icon search path. So let's just use that instead of adding
custom one.
This commit also fixes missing icon for "Add call" button in active
call window
This adds a style.css file to allow the use of custom css
Fixes https://source.puri.sm/Librem5/calls/issues/115:
- Making the phone number larger
- Moving the delete button to the bottom
- Rounding all buttons, and making the grid buttons circular
- Making the call button a bit less wide
* Make the Answer button look nice and laid out properly.
* Merge the time and status labels, displaying simply the text
"Calling..." until the call becomes active and then the call time
afterwards.
* Fix info display bar in both the call and main windows so they use a
GtkRevealer and work a lot better.
* Add a "new-call-symbolic" icon for the "Add call" button.
* General tweaks and clean-ups
