Add a "Usage" key to the repo section of the config which allows for the
tokens "Search", "Install", "Upgrade", "All", which correspond to values
in the alpm_db_usage_t enum. Users can specify "Usage" multiple times
for a given repo, or multiple flags per "Usage" line and they will be
OR'd together. If unspecified, the default is full usage of the repo.

I'm wondering if there ought to be a way to specify 'None' here, which would
basically restrict you to only listing the contents of a repo and nothing else.
