Universal Content Broker (has ucp) which do things like convert files to strings in content broker world.

mmeeks: so - I renamed the old LGPLv3 webdav code to webdav-neon, and imported
the (not built) surf webdav ucp into the old space. so that in future, we can

volunteered to do some comparative analysis of the two codebases to decide which
is best for what etc.
