Having CRLF files in the repository with eol=crlf breaks just about
everything, e.g. any rebase/merge involving these files would fail.
Try to fix this by making sure the files use LF in the repository and CRLF is
only used in the working copy.
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.
