[Ironruby-core] Mono build trouble

[Sanghyeon Seo]

First, thank you for getting the new revision out.

SVN r114 introduced a change to context.rb. Instead of using
/recurse:*.cs, it now gets the list of C# files to compile from
*.csproj files using REXML. Unfortunately, all paths in *.csproj files
are Windows paths, and the build fails.

Reverting the change locally seems to work fine.
