Added/Modified Items List, Adding table columns

Added a few extra items to the drop down lists and changed some others.
Also changed the player info tables a bit to show more info (date first
seen).
Fixed regexp typo

Database cleanup options have yet to be fully implemented, but noticed
this small error >_<
Put DB connection in Try-Catch block

To prevent DB connection info from being displayed upon errors.
Fixed array search case sensitivity issue

Was not correctly matching item classnames.
JS Function Fixes

+Added new item classnames
+Changed table layout (now shows days/hours players have been alive, and
date first seen, also changed format of coords to match that of input
for setting player position)
SQL Query Changes

+Changed the way time alive was retreived, now gets hours alive in SQL
(conversion to days done in JS)
