Fixing timeline js timing out (#483)

Issue if being cause by selectToUISlider() plugin. It calls a
jQuery::width() on each of the elements it creates for the month names (it
can go up to quite a few on large time spans)

Updated function to call jQuery::width() only on the first element of the
set, and letting jQuery handle the css() call for the whole collection. I
suspect it will use each() internally, but I also suspect it will have
smarts to do it more efficiently.

Fixing logging for uncaught exceptions

Kohana's log function accepts an array of arguments, but the default
exception handler doesn't really do that, which logs a whole bunch of
useless messages.

This fixes that. :)

Fixing boolean check for stats (Issue #1270)

eaf1a69 half fixed the issue with connection problems.

The check for $xml == false is always true, and so the stat_id and
stat_key returned by the tracker are never saved on the database. This
never lets new deployments get their stats started.
Bug when updating email on /admin/profile (Issue #1260)

Code is loading user by email to check password typed. If user is updating
their email password can never be verified. Changed code to load user by id in session instead.
