Part 1 of 5: Optimize the resource merge process, Introductions.

Introduces the AndroidDataSet, a holder for DataResources, that will be the building blocks of the revised merging system.

Also introduces a DataResource implementations:
* FileDataResource, which represent non-value resources. These do not need to derive the resource symbols they provide.

This will replace the current ResourceSet, ResourceMerger, and ResourceMergerWriter with more efficient (e.g. fewer copied files) operations.
