Subject: [PATCH] remoteSearch: Don't add providers more than once

Currently we load all search providers from XDG_DATA_DIRS, so if
the same provider is installed several times in different directories,
we happily show duplicate results. To fix, keep track of all remote
providers we add and skip those that already have been loaded from a
different directory.
