more progress on windows compilation.  documented in https://github.com/RobotLocomotion/drake/issues/42
got rid of matlab_cpu dependency (since it's hard to get on windows, and wasn't actually being used!)
close to working matlabroot logic
find mex executables on windows by looking for .bat files explicitly.
compiler checks work for visual studio
mex argument processing starting to work for visual studio (still need to handle all the arguments)
added mex compiler options for visual studio
have to compile on windows with make then cd pod-build, nmake.  but it's finally working to the point that i'm getting useful errors/warnings from the compiler
progress on building for windows
handle paths with whitespace
moving cmake to submodule
pulling in cmake submodule
adding release filelist logic
updated submodules
use CMAKE_MAKE_PROGRAM instead of MAKE, which solves the nmake issue on windows
use relative file paths in build/matlab/addpath_drake and build/matlab/rmpath_drake
fix release filelist
more robust logic for case when lcm does not exist
getCMakeParam was failing if cmake was not found.  now it fails more gracefully
Fix cmakeparam logic
better check for vrml viewer and more helpful message if it is not found
