Go mono!

This pull request essentially enables System.IO.Abstractions to be used on Mono. In particular, it fixes #82 as well.

The trick which got me into fixing it actually is to remove the recursive access for MockFileSystem.Directory (see 3e17340). The rest was to fix all backwhacked tests to run as well on slashdotted systems. I followed a lazy strategy by introducing a MockUnixSupport helper. I aliased it in tests with XFS for the sake of brevity.

All tests pass both on Mono and Windows.

I tested on Win7 w/ Net4 and Linux 3.16.3-1 w/ Mono3.4.

@nosami @tathamoddie It was sort of a stretch to get this running on Mono as well, but I suppose it's worth the effort. Feedback and comments welcome.

Howdy. Had an issue with the build on first pass, due to package restore not being run, because of the nuget.targets reference being removed. I've now updated the build process to include the restore step, without requiring the MSBuild customization, as that's the more modern way to work anyway. We're all green now, so happy to merge this in. Thanks for the contribution.

+1 I'm happy that this was merged in. Hopefully, I'll be able to use this now!

The nuget.targets thing is usually just case sensitivity issue. It should have been NuGet.targets but seems like that's been resolved now.
