Add ability to provide an alternate set of configurations for the settings files. This works like this: If you want, create a settings file called "configuration.xml" (this can be either app or local, but really should be local, since putting it in the app would defeat the purpose a bit). This file can have a setting named "folder" and if it exists, then any settings found in the "folder" subfolder of the "settings" folder will be added on top of their settings. See ds_cinder/doc/example_settings/configuration.xml and 1920x1080/ for example and explanation.
Realized something about the config folder order of precendence that was wrong from the docs.
Add support for a resource type of 'a', which is just converted to video, because that's the system currenly used to play audio files.
