Build failed on Linux and OSX
There are 2 problems:
1. (Affects OSX and Linux) Wrong path to "packages.config". Xbuild tried to search it in SolutionDir, not in ProjectDir.
2. (Affects Linux) Linux has case-sensitive file system, so xbuild couldn't start "nuget.exe" because it is "NuGet.exe"
I made a pull-request https://github.com/clojure/clojure-clr/pull/13
linux, osx, mono
