Theme: set default theme 'Flatty Dark Blueberry'

The theme is now stored in generated C code,
which can be extracted from existing user preferences.

This theme can then be used for version patching themes
instead of duplicating values

Note that theme versioning has been removed,
since minor changes from now on won't apply well on top of 2.7x theme.

Theme colors from interface_widgets.c have been removed too.
