Verbose page titles again

Adds support for more verbose page titles based on current
page and action by user and removes sort by options from
search form as they're obsolete by column links.

This removes the need for a timeout page (and probably hacker.php) and
moves the login form and status to the header. If your login times out
you won't lose your place anymore and links will always work. Works
for me but at the moment index_po.php is imported in aur.inc which has
to stay until the translations from it for login are moved to
aur_po.php.

Simo's original commit text:
 The idea of safe flagging is unclear, poorly named, misunderstood,
 and not even used. At the time this patch was created, less than
 a third of the packages in unsupported were flagged safe, and less
 than a tenth of users knew how to interpret it.

 The safe flag has been replaced by a disclaimer on the main page.

Added AUR_VERSION to config file, so now we should only need to
change one location. KISS ftw.

- Replaced all occurences of mysql_escape_string()
  with mysql_real_escape_string().

- Replaced all occurences of mysql_escape_string()
  with mysql_real_escape_string().

My Statistics instead of User Statistics. For TUs show number of packages they flagged safe, not number of their packages that were flagged safe.

this will require some translation updates

closes bug #3023

fixed bug in the new update list where it doesn't list most of the updated packages, listing instead mostly new ones
