[isf-wifidog] At long last, dynmic abuse control implemented!

[Benoit Grégoire]

Early, but relatively feature-complete implementation of Dynamic abuse 
control, to curtail chronic bandwidth abuse (see 
http://dev.wifidog.org/wiki/doc/developer/TrafficShapingIssues)

	* Authenticator.php:  Fix SQL error closing connections.
	* auth/index.php:  Probably fix the "Access denied" message when user click 
twice problem that resurfaced.
	* At long last, implement operational Dynamic abuse control (out of the 
embryo of the token architecture)!  Configurable in Network preferences if 
you have the permissions.  Unlike static limits, this is a sliding window 
(typically a month) during which user have a bandwidth and connection 
duration limit, per node, and totalled throughout the network.
	* UIAllowedBandwidth:  New, simplistic content type to show the user how much 
of his allocation he consumed.  Off course, the goal is actually to make it 
into a pretty graph....
