Fixed a bug with shaders unrelated to the dreaded black screen of death. also removed shaders, due to said black screen of death.

If you'd like to play with shaders (and give feedback on their functionality, which would be rather helpful) navigate to the mod's directory (steamapps\common\The Binding of Isaac Rebirth\mods\crawlspaces_rebuilt<random numbers>) and drag "shaders.xml" into the content folder. Who knows, they might work just fine for you.
I suspect this may be a hardware specific issue? which would be a lil tragic cause I have genuinely no clue how to approach patching something like that lmao. but it could still just be some strange situational quirk I wasn't able to catch in testing. Alas, I'll probably wait for a bit more feedback on its functionality or lack thereof before dipping my toes back into fixing this.

Happy anniversary to this dumb mod!

-works with fiend folio now
-added support for mod config menu
-gravity is now always aplied to players whenever they aren't on a ladder (disable with the config menu to escape possible softlocks in modded rooms lol)
-learned to write shaders and redid the whole lighting system (you can still revert to the old buggy vignette if you wanna with the config menu)
-poop variants other than the default no longer get messed with by this mod, and should look as expected
-spikes in crawlspaces now have custom sprites to fit with the environment better
-uuuuh. i fixed that one bug with stageAPI. and maybe changed a few other little things.
-lots of under the hood stuff that nobody needs to hear about

Added global variable "CrawlspacesRebuilt" to allow for inter-mod compatability.

Ok but fixed for real this time...

Fixed vignette effect not scaling to fit abnormally sized windows propperly
