GUIScript: celar the MessageLabel in DropDraggedItem
LoadGame: load map before refreshing effects

fixes the blue flicker on map loading and also the message order in the MTA. (loading tip, effects, other)
LoadScreen: add a newline after "hint" (in MTA)
Fixing a slew of clang anylizer warnings

some of the asserts could probably be addressed in a better way
TextArea: fix type conversion warnings
TTF: port to new Font interface

this is completely untested BTW. it just compiles.
