Keypad Tool and Cracker with Wire Support

This is a nifty little tool for creating keypads for use with contraptions or bases. It is compatible with sandbox based gamemodes such as DarkRP and other roleplay gamemodes.
The weapon class for giving the cracker to players or jobs is: "keypad_cracker".
If you encounter any problems while using this addon please contact me (through steam of course).
I am also a generally unbusy person so feel free to add me anyway if you're an interesting person.

Configuration
The keypad_crack_time console variable sets the amount of time (in seconds) for the keypad cracker to take cracking a keypad. This can be set in your server.cfg as so (e.g. 10 seconds):
keypad_crack_time 10
