Convert dashboard ajax code from Prototype to jQuery

Check if a widget is null before testing a property. Fixes skipped updates on certain widgets (like the gateway widget) if someone doesn't have the cpu widget file on their fs (which a clean install does not).

Remove unnecessary variable and fix loop test. Corrects AJAX update of last gateway status table cell (it was never updated before)

Fix ajax updating of fields when the CPU graph widget is not in use.

a little cleaner JS

Sajax is no more, long live Prototype
This eliminates one AJAX library, but not all "non-Prototype" AJAX code

Make use of Prototype-ism's in sajax.js - first small step in attempting to remove sajax from pfSense

• Make function opening braces uniform.
• Minor documentation additions

Ensure that the gateway widget exists before populating data during ajax calls.

Change to 11 second refresh, a lot of underlying information refreshes
every 10 seconds.
