Fixed the Code of two failing relativ paths tests. Made getting the AbsolutPath easier. Added NCrunch Configurations

Fixed DotSettingsProcessor.cs to use the DiretoryName of the Settings File

Using Path.GetFullName() instead of a custom method to get the absolute Path to a file.

NCrunch Configuration added, does not harm if some don't has NCrunch

Btw. sad that there is no TeamSharper.sln.DotSettings ;)
