Some OOT transfers, some renaming, etc (#75)

* Progress on various files

* gfxprint stuff

* split some rodata, add iconv for rodata string parsing

* z_std_dma rodata

* 2 nonmatchings in gfxprint

* mtxuty-cvt ok

* more

* match a function in idle.c

* progress

* Cleanup

* Rename BgPolygon to CollisionPoly

* progress

* some effect stuff

* more effect progress

* updates

* made suggested changes

* z_effect_soft_sprite_old_init mostly ok
