Adds SLURLs to antispam notifications
Reduces weight of antispam to either global queue, multiple queues, or none
Renames variables to make more sense
Repositions code, cleans up code, uses modern C++, etc
This fixes a bit of a leak or two, especially with antispam turned off!
Also fixes the endless leak of queue expansion by cleaning up while idle
When changing between global and individual queues, they're now purged.
Also made some improvements to previous commit, woops.
Also fix wrong logic for is_linden and chat source type for objects
Updated AntiSpam with documentation, safety measures, and better presentations and clarifications for the end-user from FS.
If it looks like something was removed from an xml, it was just moved to fall into place better with v-d.
Corrected log end message being log start message.
AntiSpamNotify setting to turn off notifications, which seemed to become a new form of spam, otherwise.
Add tool_tips to UI explaining how to make the system less sensitive.
Made defaults for antispam a lot less sensitive, so users used to the old antispam defaults won't likely need to configure the new panel.
Pull in license from NaCl... (Why wasn't it already there, Ruby?!)
Fixed spaces being where tabs should be...
Added in selective Dialog disabling, instead of just all, nice little feature in itself.
Potentially fixed a bug where sounds would be blocked when they shouldn't be... but, if this still happens, I'll put in a debug setting to disable sound antispam.
