Tag-Cloud like filtering in frontend

• Install extension
• Add a TagFilter field to your section
• In section's data-source, add the Tagfilter field as a Filters param (leave value empty)
• Now, in frontend you can control data-source filtering using 'tagaction' url parameter

Comma separated value of tag 'actions'. A tag-action is defined as <operator>:<tag>

Currently 3 operators are defined:

• a, add <tag> to filter list
• r, remove <tag> from filter list
• c (without parameter) clean filter list
