Worked on search

Added Q/A search #11 with bugs
The search forms are now on the right.
The search forms are before the results, so that they are visible even
when terminate() is called
When viewing the results, the user can see the search queries
At user search results, usernames are links to the profiles
Improved pending.php

Sort unanswered question from oldest to newest and show only the 50
first
If no questions are returned, show div#noQs
Timeasked formatted to look nicer
