fixed debugging text sometimes not initializing properly and then showing up on screen when there were no errors

just a bit of refactoring

fixed bug where if a mod function had a weird name it could break the removecallback handler causing future removecallback calls to remove all callbacks of a specific type rather than just the specified one

-added Repentogon callbacks to callback list
-much better compatibility with mods that rely on RemoveCallback

devs broke the API update

fixed the mod missing callbacks that were created using AddPriorityCallback

set the render callback to be created late instead of when the mod loads, so that way the text will display on top of anything else that gets rendered by mods (really helpful with FPS mod)

-added option for font size
-fixed the bottom text areas getting cleared if no callbacks met the minimum time requirement in the previous frame

display now shows function names (if the function has a name)
