make tag list dynamic

added a controller for tag list
start writing a filer based on tags

having some issues with scopes. Should the entire view be in controller? Probably not.
Okay, how do I share share the list of selected tags with the filter function then?
Maybe replace the tag.selected binding with a method call. The method would be a method call to a service
use ng-change on the "filter"
tests for tag filters pass, but page doesn't function properly

should probably use a proper filtering format and the $format function instead of the tag id list
e.g.
{
  'kana': true,
  'lind': false
}
finish dynamic tag filter

closes #6
now the elements in the offers list can be filtered using the tag checkboxes above the list
