    Adjusted placement of invalid 'link' elements outside of 'author' element. Feed now validates, though warnings/suggestions still exist. [Issue #1408]

when resque tried to get the constant "Mail" from the "Jobs" module it got the inherited constant "Mail" (ruby gem) instead of Jobs::Mail

This reverts commit f859904c.

locally when Resque tried to constantize Jobs::Mail Object.const_get("Jobs") returned our Jobs module but when it tried to const_get("Mail") it returned the Mail gem.
added copyright

RFC2822 specifies that you use parentheses to denote a mailbox list. Use the addr-name spec to specify a display name and the from address.
Check against the raw headers of the mail as @mail.from excludes the display name
Extract shared logic between notifier methods

This becomes a problem when having this widget
instantiated looking at the followed_tags stream
With the former code de/selecting aspects was
only refreshing the followed_tags stream, not
loading aspect stream posts

With previous css selector two textareas where
returned, causes reset of the post text when
selecting new aspects for the second time on
the left nav. Related to #2102

fixed tags#show when tag is not found

Bug introduced by commit 2b22e1da

Reopen Publisher after changing Aspect selection if there is unsent text 

make the links on featued users tile be the tag with the name in the link.  added a following count to tags
