core: Add context hinting for new feeds 

RSS-Bridge currently has to guess the queried context from the data
provided by the user. This, however, can cause issues for bridges
that have multiple contexts with conflicting parameters (i.e. none).

This commit adds context hinting to queries via '&context=<context>'
which can be omitted in which case the context is determined as before.
