- Implemented better C++ classes for handling scenes/sources/items in obs.hpp, allowing them to automatically increment and decrement the references of each, as well as assign them to QVariants. - Because QVariants are now using the C++ classes, remove the pointer QVariant wrapper. - Use the new C++ classes with the QVariant user data of list box items, both for the sake of thread safety and to ensure that the data referenced is not freed until removed. NOTE: still might need some testing. - Implemented a source-remove signal from libobs, and start using that signal instead of the source-destroy signal for signalling item removal.
