Add RemoteRepoCache and integrate it into _create_source_pool().

This adds a new setting called 'cache-server' to morph. It is None
by default and should be set to the HTTP URL of a morph cache server
to be used.

The RemoteRepoCache object provides two methods: resolve_ref() and
cat_file(), both of which wrap the communication with the cache
server and return a SHA1 string and file contents, respectively.

The _create_source_pool() method now takes a local and an optional
remote repo cache and tries to do whatever is best to resolve
refs and load morphologies for the Source objects it creates.
