Major update to Outpost support

[GoogleCodeExporter]

I've brought my personal branch up to the latest SVN version. This includes a 
large overhaul of the Outpost support so that it is now usable.

Patch is available at 
http://www.adamashley.name/stuff/pos-tracker-r206-rework-outpost-support.patch

Changes:
* Adds specific user permissions for Outpost management.
* Makes Outpost Tracker listing UI more consistent with POS Tracker
* Corrects permission checks on Outpost pages and actions
* Fixes logging of Outpost changes
* Adds a 'Desired Stock' calculation to view outpost page. This is currently 
hard coded to 60 days, I planned to make it UI controlled but havent got to it 
yet.
* Fixes POSMGMT->addstructure() so that it correctly adds a silo the same as 
addstructure.php. This method is used by the fit importer.
