fixed bug on caching and pathway workaround
Unknown property filling error log

When search engines or users open feed page of a tag, error log is filled with

```PHP Notice:  Undefined property: stdClass::$title in /home/joomla3.2/public_html/components/com_tags/views/tag/view.feed.php on line 60```

I guess author wanted to get title of the tag, so I changed the code accordingly
Update view.feed.php
Fix Search Filter activation in com_users

In Search Tools, filter activation not working as expected.

Search Filter for activated users is not displaying super users as activation value is '0' in database.
This PR fixes it by adding 0 as a value for activated users.

Search Filter is not working for Unactivated users (activation key is not anymore 32 characters length).
This PR fixes it by controlling if activation is > 1. (which means that an activation key has been generated)
