Configurable CModel mapping?

[bondjimbond]

It would be difficult to make this module 100% useful for all content models. For example, in this branch I added a mapping for 'txt' => 'islandora:sp_remoteMediaCModel', for my custom Remote Media content model. But it is conceivable that someone else might use txt for a different CModel.

Suggesting there could be an admin form where these mappings can be configured by the user and customized as needed to add more filetypes and CModels without hitting the code.

(Or if you're OK with my Remote Media update, I could just make a PR for it.)

Interesting use case. The extensionToContentModelMap is assuming mappings that a vanilla install may have, not one with a lot of custom content models. For example, it's not clear to me that 'txt' should always be mapped to islandora:sp_remoteMediaCModel - so having a way of configuring this on the fly with an admin form when creating different types of compound batches could be a useful feature.

I think the core Islandora module provides a hook to modify MIME type mappings. Maybe something similar here would be useful?
