Touched up awavefront once more to conform to permissions and be used as intended

Added debug settings OBJExportNotifyFailed and OBJExportNotifySuccess for whether or not to notify about OBJ Exports failing or succeeding respectively
Moved exports back into tools submenu, there's not enough variety to justify a menu dedicated to exportation
Removed hardcoded "Insufficient Permissions" string, there's already a notification for this.
Implemented proper permissions checking, along with own Avatar Export.
