Fix formatting in if()

Detect and use a sample voucher page when vouchers are defined. Otherwise default to the user/pass default page.

Actually it should test the other way.

Ticket #846. Do not try to add an interface to the bridge during an event of LINK_UP.

Escape $ variables

Add Captive Portal voucher database sync to secondary nodes. How this works is you designate one of your access points with a voucher database as the master and then on the slave nodes you setup the 4 fields on the voucher edit screen. This will then sync the voucher database and anytime someone attempts to authenticate the slave nodes will use XMLRPC over to the master node to ensure that the voucher has not been used, etc....

Fix some PPPoE server radius variable references. Fixes #853.

Revert the top field change shift as these break a lot of other installs.

Limit description of rules to 64 chars as that is what pfctl will accept.

Allow carp interfaces to sit on top of aliases. Also add safety belts to ipalias deletion for this to avoid breakage. Trigered-by: http://forum.pfsense.org/index.php/topic,27834.0.html
