[web-devel] Simple mime-type package

I am not especially excited about it. The fact that some mime-types  
are hard coded, and others are not is an annoying 'inconsistency'.

There is no way to extend the list of supported types in user apps.  
And typeByExt has a rather limited set up extensions, declaring  
everything else to be application/octet-stream.

The use of a type for the mime-types implies that you want to be  
pattern matching on the constructors in your code ? Can you give a use  
case for that ?
