Bug 934739 - Part 2: Add pattern matches to install manifests; r=glandium

This patch adds pattern matching entries to install manifests. We store
metadata necessary to construct a pattern match at a later point in
time. When we convert the install manifest to a file registry, we
resolve the patterns using FileFinder.

The build config logic has been updated to store support-files values as
pattern entries. This should resolve the clobber needed issue and make
the local development experience more pleasant as well.
