Get rid of version-specific MSVS project files, we can reuse the same projects
for all MSBuild-based versions, i.e. 2010, 2011 and 2013.

Start moving away from files.bkl as the primary source for the files -- and
away from bakefile itself as the make/project file generator -- by storing the
list of files in a new build/files file and provide a simple build/upmake
script for updating files.bkl and the manually maintained MSVC10+ projects
from this file contents.
