I've implemented primitive filtering, and the ability to select posts.  I am not yet posting them back to the server though.
Added method to ensure we can get unique groups and posters from the NZB Results.
Implemented the basic filters for group and poster (using a typeahead control that I built).
Added a dropdown button control (works much better for filtering).
Updates to make rendering better on iPad.
Implemented the "Show/Hide" functionality for the forms.
Implemented the post functionality.
