Bug 1755919: Adding related tags page and adjusting tag filter

This patch contains the following:
- created a relatedtags.php page + json file + template to handle the
viewing of related tags for a user, the differences for this to
tags.php page are:
-- it can be viewed publically
-- it requires a tag and viewid

- Adjusted the filters for blog/blogpost, plan/task so they appear
under their own filters as well as 'text' filter

- adjusted the dwoo function list_tags so that we can pass an array of
viewids/tags and/or just a view id

-adjusted the portfolio_search_* functions so they would work for both
my tags and related tags pages

- fixed a filter js problem for tags.php where choosing the filter was
not updating the displayed filter string
