- Add property list callbacks to sources/outputs/encoders so that if necessary user interface can be automatically generated or perhaps a property list widget can be used for them. - Change some of the property API names. obs_property_list_t felt a bit awkward when actually using it, so I just renamed it to obs_properties_t. - Removed the getdata/setdata nad getparam/setparam functions from sources/services, they will be superseded by the dynamic procedure call API.
