Add possibility to filter by more than one criteria at a time

This new version of the TagFilterSortModel actually accepts
*any* new MultiFilterInterface.

So, how to use it to create a new filter:

Implement a class that inherits from MultiFilterInterface

Implement the filterRow method

TagFilterSortModel::instance->add( myClass );

and you are done.
