Job: Fix up an old addon

*Budget and due date are negotiable* Fix up an old mod called Wrench Toolset, it basically lets you use hammer while inside of Garry's Mod. In the current version of Garry's Mod it is broken so fixing and adding a few features is required to get the mod working again. The only thing I ask is that you have good LUA skills and past work you can show me. Thanks for reading!
