Work in progress- relative URIs

Making template and CSS URIs relative to the library in which the type which is annotated resides.

Also making all URIs within the template and CSS files be relative to those files.
Additional cleanup items

 - package-relative URIs are now 'packages/' rather than '/packages/'.
 - Support for mirrorless mode with a transformer. This transformer generates
   one large table for type->URI lookups.
 - Integrated with tip-of-tree Angular

This generates a global table of type to URI lookups
