Quick and dirty: add back the HTML form to create nodes on mode:root.
Stubs out a first pass at a header template.
fix sitemap generation to use full paths to objects
fix computed size predicate
add a search form for text/html requests to field search without a query parameter
use uriinfo to build paths
consolidate common header data
add RDFa to html triples serialization
Removes old Velocity templates from http-api
Removes hard-coded "/rest/" from @Path annotations. The path "/rest" is now set in web.xml (and so is technically variable).

jersey-servlet is no longer greedy, so we can serve static resources. This also could have been accomplished by setting
the Jersey SpringServlet as a filter and then using a regex to exclude static resources, but I didn't see a reason to favor
that approach

Also adds a favicon to webapp/
Adds a stub for an index.html page
