UI: Use "source_create" to add scenes to listbox

Browse Source 
Instead of manually having to call AddScene each time a scene needs to
be added, use the "source_create" global OBS signal to detect when a
scene has been created, and add the scene to the list automatically.
Allows the ability to add scenes to the main user interface via libobs
API.

Closes obsproject/obs-studio#1226
