Fix tile props and traps

re- did the tiles
Boss Spawning/ Gate Dropping

This is going to be redone, but it does work
Merge with origin
some fixes
engleton bullet and crazy laser fix
Remove old file in game mode

Removed file that was deleted, would cause error upon startup
Saw and Spikes collision redone/ animated

both traps now animate and only do damage when you touch the
spikes/saw, not the trap as a whole
some particle fixes
Merge LevelGen2 with master
lots of stuff

updates tiles, some particle fixes, engleton shot should now match
distance it actually can hit at, and some imports. Also did a lot of
terrain fixes but a crash somehow lost the majority of the fixes :(
Merge branch 'master' into UserInterface
