Some improvements to Dark AOSP theme

The only plain (without key borders), dark, and with symbols keyboard theme needs some improvements for simplicity lovers.
Better readability and contrast.
1. Large font size
2. White text color
3. Sligtly bluish background (Gboard-like), feels more lively than dull gray
4. Adjusted vertical and horizontal spacing for popup characters to appear near to main character
5. New Ctrl key icon to match the theme
