generated mapfile and symfile in gitignore
finally compile multiple objects

pokecrystal.asm doesnt really make sense now so its gone

add includes.asm so objects have a standard include set
version-neutral build targets

pokecrystal will probably never build gold/silver, but who knows
version-sensitive objects for egg moves and evos/attacks

this way main.o and wram.o are version-neutral
version checks for event script commands and move in related asm
split event handling into engine/events.asm
move map groups into maps/map_headers.asm
buena text
split more event handling out of main
objects for event handling and scripting
Makefile: more readable object list
forgot the new pokecrystal.asm
Merge pull request #217 from yenatch/more-objects
