Ethan Atkins 2b2b84f589 Use FileTreeDataView to collect files
Now that we have the fileTreeView task, we can generalized the process
of collecting files from the view (which may or may not actually cache
the underlying file tree). I moved the implementation of collectFiles
and addBaseSources into the new FileManagement object because Defaults
is already too large of a file. When we query the view, we also need to
register the directory we're listing because if the underlying view is a
cache, we must call register before any entries will be available.
Because FileTreeDataView doesn't have a register method, I implement
registration with a simple implicit class that pattern matches on the
underlying type and only calls register if it is actually a
FileRepository.

A side effect of this change is that the underlying files returned by
collectFiles and appendBaseSources are StampedFile instances. This is so
that in a subsequent commit, I can add a Zinc external hook that will
read these stamps from the files in the source input array rather than
compute the stamp on the fly. This leads to a substantial reduction in
Zinc startup time for projects with many source files. The file filters
also may be applied more quickly because the isDirectory property (which
we check for all source files) is read from a cached value rather than
requiring a stat.

I had to update a few of the scripted tests to use the `1.2.0`
FileTreeViewConfig because those tests would copy a file and then
immediately re-compile. The latency of cache invalidation is O(1-10ms),
but not instantaneous so it's necessary to either use a non-caching
FileTreeView or add a sleep between updates and compilation. I chose the
former.
