RedmineUP Agile plugin compability

[kusmierz]

I'm not good with redmine plugins, but I achieved what I wanted to do. Basically I was trying to integrate tags filter into RedmineCRM/UP Agile board (where is misses). Maybe somebody could make ixti/redmine_tags' PR from this, so it would be permanent, better solution.

This is diff for RedmineCRM/UP Agile Plugin v1.4.3.
