AGI: graphics rewrite + cleanup

- graphics code fully rewritten
- Apple IIgs font support
- Amiga Topaz support
- Word parser rewritten
- menu code rewritten
- removed forced 2 second delay on all room changes
  replaced with heuristic to detect situations, where it's required
- lots of naming cleanup
- new console commands show_map, screenobj, vmvars and vmflags
- all sorts of hacks/workarounds removed
- added SCI wait mouse cursor
- added Apple IIgs mouse cursor
- added Atari ST mouse cursor
- added Amiga/Apple IIgs transition
- added Atari ST transition
- user can select another render mode and
  use Apple IIgs palette + transition for PC versions
- inventory screen rewritten
- SetSimple command now properly implemented
- PreAGI Mickey: Sierra logo now shown
- saved games: now saving controller key mapping
  also saving automatic save data (SetSimple command)
- fixed invalid memory access when saving games (31 bytes were saved
  using Common::String c_ptr()

Special Thanks to:
- fuzzie for helping out with the Apple IIgs font + valgrind
- eriktorbjorn for helping out with valgrind
- LordHoto for figuring out the code, that caused invalid memory
  access in the original code, when saving a game
- sev for help out with reversing the Amiga transition

currently missing:
- mouse support for menu
- mouse support for system dialogs
- predictive dialog support
