--support painting based on the active window scheme.
Added a schemecolors class for this and updated
abstractwindowinterface to provide tracking for windows
color schemes.
--the wayland interface couldnt orchestrate correctly
with the corona and the application exit. The whole
architecture changed and the window manager now is
provided by corona and corona is also responsible to
keep only one instance of it and close on exit.
