Fixes and SDK Updates

I have made two commits that are useful for those starting with the repo. The first adds the debug folder for the STLPORTS SDK into the repo. You can't compile the project without copying these files to the right location so it should be included. The second updates the Boost SDK to the version shipping with CryEngine 3.4.5 so it should also be included.

It compiles, but I haven't been able to check the result yet due to a DLL error when loading Cry editor. Compilation was using stock install of VS 2010 and Win 7.1 SDK. Will try again once I have 2012 installed.
