Wraith

Adds boss monster in the likes of the Jabberwock and the Sludge crawler
Removed sundeath from wraiths
Fixed the missing value in savegame.h
Merge branch 'master' into Wraith
Rookie errors

Fixes three errors that I found
Tweaks the Spawn and behavior of the Wraith

It now spawns in the cult cabin first floor, also I gave it sundeath and
removed its ability to follow you so you could kill it by opening all
the windows of the main room to let light in
Remove needless redundancy
SDL2 Alpha
Replacing tick based try_update.
Disabling cache to avoid SDL2 bugout.
Removing my fingerprint from makefile.
Fixing input lag (my fault).
cata_tiles update 1
cata_tiles update 2
Change all SDL_Surface to SDL_Texture

Had to rearrange initialization to make things work right.
Fix zoom + misc cleanup
Tweaking rotation logic.

If this doesn't work I may have to bring back the rotation cache.
Hunch #1

First of two hunches I can trying to get the offsets working right
without having to use a rotation cache.
Fallback categories for tile drawing.

For instance, "unknown_monster" will serve as fallback for monsters without sprites, and "unknown_monster_MAMMAL" will serve as fallback for species MAMMAL without sprite. Similarly. "unknown_item" will serve as fallback for items without sprite, and "item_unknown_CONTAINER" will serve as fallback for containers with no sprite.
Small changes to HoderTileset to demonstrate tile category fallback behavior.
