Title: Move bulk add mappings filters into a module

* Previously, we had to duplicate the same filters across controllers
with slightly different options
* Since we're already including the module, make that include happen
via a method call instead
* That method call passes through the options to before_filter
* Since the use of the filter also depends on find_site, move that
into the module too
