Add build_id_path for Strings

Fix for #71

[visoft]

Could you add a spec for this change? It shouldn't be too hard given such a simple tweak.

Sorry, I'm working on Ubuntu and have currently no setup to run the specs on Windows with IIS

You don't have to create or run the Cucumber features, you can write an RSpec spec. For those I use "fixtures" of the EDMX metadata and the results of a query (typically). Take a look at some of the specs already out there. In your case you can probably just get away with a copy of the metadata (found at http://yourserver.com/$metadata).

I have installed a Windows system with Ruby (Thanks to rubyinstaller.org !) I will prepare some specs next week and update the pull request

This has been merged into the develop branch. Thanks so much!
