Merge branch 'tests'
Add code to handle an unexpected/inappropriate reply type for our query
Test real query for "yturl" against a known pickled version
Merge branch 'api'
Generalise performSearch to allow different query types.

This will allow us to avoid code duplication when doing "msearch"
queries.
Add msearch functionality.

This also generalises parseSearch into parseAURSearch, as both the
"search" and "msearch" queries both get back pretty much the same data
format, so it doesn't make sense to duplicate code.
Merge branch 'api'
Test real AUR queries.

Obviously since these use live data they need to have an eye kept on
them.
