Minor fixes

Changed the path for relayutility to _relayutility so we don't collide
with any legal database names

Put in a .gitignore to ignore a dynamically generated test file that I
should really move to temp

Put in code to munge up some wrong CouchBase responses to the right CouchdB
format so PouchDB will work and fixed a chunking bug.
