- Signals and dynamic callbacks now require declarations to be made before being used. What this does is allows us to get information about the functions dynamically which can be relayed to the user and plugins for future extended usage (this should have big implications later for scripting in particular, hopefully). - Reduced the number of types calldata uses from "everything I could think of" to simply integer, float, bool, pointer/object, string. Integer data is now stored as long long. Floats are now stored as doubles (check em). - Use a more consistent naming scheme for lexer error/warning macros. - Fixed a rather nasty bug where switching to an existing scene would cause it to increment sourceSceneRefs, which would mean that it would never end up never properly removing the source when the user clicks removed (stayed in limbo, obs_source_remove never got called)
