Build standalone UI program (emulator-ui).

This changes introduces a new program, called emulator-ui
that only contains parts necessary to display the UI (and
removes anything related to CPU emulation).

This is only a skeleton right now, since it is not capable
of launching a core, or displaying anything meaningful,
except the skin, trackball, respond to commands (e.g.
change layouts with KP-7 and KP-9).

Later changes will introduce core launching, communication,
etc...
