Added support for hyphens in embedded resource folder names.
When msbuild compiles embedded resources into assemblies, hyphens are replaced with underscores in foldernames. This causes a mismatch when the EmbeddedStaticContentConventionBuilder is used to locate a resource, as it is still expecting the folder names to contain the hyphens.
Added StaticContent helpers

Fixed issue with single wildcard
StaticContentConventionsBuilder uses a static Dictionary<string, responseFunc>.

This can lead to unexpected behaviour when there are two Nancy engines in the same AppDomain that differ by rootfolder but use the same path (e.g. index.html) being served from two directories.

Key on a new object that is both root and Path.
