Dweller 1.22.0

This release contains a few performance improvements and stability fixes that should speed up key areas of the game. The major performance bottleneck right now, especially on Android, is the actual rendering of graphics. I will have to look into switching to another graphics engine for Android, but it will have to wait a little while longer.

The new version also fixes some recently introduced bugs related to the Sewers and to poisons ans poison immunity.

#415 Improve performance
#416 Doors and chests should be generated in the sewers
#417 All undead should be immune to poison
#418 Horned Helmet graphics is off by one pixel
#419 Oozes should be immune to poison
#420 Fix problem with poison immunity
#421 Improve speed when changing orientation [Android]
#422 Effects with a 1 cell radius incorrectly affected some targets twice
