* Updated copyright notices for 2020
 * Reimplemented the UI objects in Python
 * Added the E_SDL_EVENT_TYPE, E_SDL_BUTTON_MASK, E_SDL_KEY_STATE, and the
   E_KMOD enums for the Python bindings
 * Fixed the bee.kb.append_input() Python binding to take the keysym and mod
   instead of the keyname
 * Changed ObjScript::mouse_input() so that not all event parameters are sent
   * This is to reduce lag from constructing the Variant map when the mouse is
     moving a lot, one of the easiest ways for the user to generate dozens of
     events per frame
 * Changed main() so that the main level is loaded before running cfg/config.py
 * Moved cfg/ inside main/
 * Moved resources/ into maps/lv_test.tar.xz
 * Updated the valgrind suppresions
