Title: pull cask loading out into classes

- introduce Cask::Source to encapsulate different types of loading
behind a consistent interface
- mostly this is method-level reorg, kept refactoring of the internals
of these methods to a minimum for this pass
- this is preparatory cleanup for adding the ability to represent a
cask without a backing ruby file
