Title: Turrets shouldn't shoot through walls, mobs shouldn't walk against walls

I've implemented a working isTargetBehindWall using the code of checklos by Mikevin (https://github.com/rCatacombSnatch/Catacomb-Snatch--Reddit-Edition/commit/1684b3e1a1227b2ac119661ec97662275c4b521b)

I've also added some code which should make the mobs move more through the map and don't stick against walls.
From the tests I've done the difference is quite noticeable.

(I've wrapped the code inside try blocks to catch NullPointers when the code tries to get a Tile which doesn't exists - I'm sure there is a better method but I didn't feel like hardcoding some levels value)
