Move FileEnumerator to its own file, do some refactoring.

It creates a class FileInfo to contain the details rather than using a platform-specific typedef. This allows the accessors GetName, GetSize, etc. to be moved directly to this class (previously they were static helpers on the FileEnumerator class) which makes a bunch of code much cleaner. It also gives reasonable getting and initialization which the previous version lacked.
