Subject: pacman: add front end support for repo usage level

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.
