Finalised directory/namespace changes

Nothing compiles, because of a few pending changes (in Card) and some
nonfinished code that definitely shouldn't compile (in ui::text::Trick). Other
than that everything seems to be fine.
Merge branch 'master' of https://github.com/mike1729/BridgeTCS1

Conflicts:
	src/ui/text/ApplicationView.hpp

Application is int viewmodel, not bridge.
