Heads up on URI changes

[Joe Shaw <joeshaw novell com>]

Hey,

I just checked in some fairly large changes to the way we were escaping
URIs, in the hopes of putting three separate bugs finally to rest and
cleaning up some fairly old and crufty code.  I don't *think* it should
change anything in terms of index/database compatibility, but keep an
eye out for any missing results, exceptions while indexing, or problems
opening results in beagle-search.

Thanks,
Joe
