Unisec Keypads and Fading Doors

#Version 1.2.0#

##Changes:##

1. Added Wire output for access granted/denied.
2. Added optional direct lockpick support.
3. Some Sandbox support added.
4. Added compatibility with most other keypad cracker scripts, including but not limited to deployable crackers, door charge, and the default cracker.
5. Map cleanups now restore permanent keypad/doors after removing them.
6. Fixed a couple errors.

##Notes: ##

1. A lot of people don't realize that if the door is flickering it's because something is in the way. This is a feature which is made to prevent players from being stuck in the door. If you don't want it, you can disable it with usec.Config.NoStuck = false. Keep in mind that if the door is nocollided to a prop, it won't consider it as in the way, so if your door is flickering from your own props, just nocollide them to the door. :)
2. You do not need to add each usergroup to the permissions and limits lists. If you add ["donator"] = 5, and the admin usergroup is above donator, you can just leave it at that. The limit and permissions run up the chain of inheritance.
3. Please update your config file to contain usec.Config.LockpickAllowed = true/false
4. Thanks again to all my dedicated bug-squashers and feature-requesters. You guys rule!
