libobs: Add global source filter add/remove signals

Browse source 
Adds global signals for when a filter is added to or removed from a
source. These will be helpful for listening for changes to a sources
filters without having to attach and detach a signal handler, which
would be annoying in the context of for example context menus which
change sources rapidly.
