Mapbase Demo Maps file

A base mod for Source 2013 which expands and improves the toolset available to modders, augmenting other maps and mods for development purposes. It contains new logic entities, new I/O and keyvalues, a custom implementation of VScript, custom shaders, countless fixes, and enhanced FGDs all in one single package. Mappers would create their maps based off of this mod and larger mods with their own unique changes would draw from Mapbase's code and assets.
