Load, timers, and window modes.

- Loading games is now working, arbitrary maps and locations can be loaded.
- Location coordinates are saved as float, for more precission when loading.
- Implemented opcodes: STTIM, WSPCL and WMODE.
- Timers are implemented. They can be created, updated and displayed, with their own characteristic font.
- All variables read or written in the field scripts are now grouped in the memory banks. No more friendly names (but they remain as generated comments, for clarity).
- Location name is now persistant between map changes, unless changed by a script.
- Window modes: Transparent, translucent, and non-closeable windows are implemented.
- Name menu now resets cursor when shown multiple times.
- Basic implementation of bit operations in Lua scripts (still unused).
