Update: INFINILOOT v0.0.8.19

CHANGELOG (v0.0.8.19):

Mostly just more rendering infrastructure being added - but, two major things happened in this update:

- World size is expanded, and a camera was added that follows the player character. Side note - world is currently really big (4x what it was before), so early waves in this patch will feel really slow. Gonna work on that later. 

- Added a tilemap renderer. You will immediately notice a grass/dirt tile pattern as the background instead of the plain dark blue background it once was. The grass/dirt looks really bright, not exactly the feel I am going for, but this update is less about cool graphics and more about the fact that I got tilemaps working!
