Updated gameinfo.txt with VPK file paths

An updated gameinfo.txt that finally adds proper VPK file paths. This means that modders (especially Hammer users) will not have to copy and paste the file paths again if gameinfo.txt is modified; which happens occasionally after an update.
This line isn't used in recent versions of the tools, question is, are gmod's tools recent? Last time I tried I had to switch to source2013's hammer since gmod's was missing some vital files...
