- Removed the inf2 = TRAP of FirePillar and Spider Web so they are blocked by Land Protector.

- Renamed skill_landprotector to skill_cell_overlap since that is more coherent with what that function does now.
- Corrected fog of wall, so that the deleted/doubled-duration effects are calculated on a cell-by-cell basis.
- Updated Land Protector: It will now delete/block effects of ALL ground skills EXCEPT: Song/Dances/Traps (encores are still blocked). Land skills blocked/deleted by LP also can't be casted on top of an existing LP. The code uses the inf2 value of the skill to determine if it is a song/dance/trap.
- Ganbantein, mimicking LP, will now also remove ensembles.
