hoodie on linux

Hi,
this is the stuff I hacked this afternoon at the couchdb.conf in order to get hoodie running on my ubuntu machine. It should work on other linux distr. as well. There is pull request for node-multicouch that this one depends on: https://github.com/hoodiehq/node-multicouch/pull/1
As it is late and I'm getting lazy, I put the example for an nginx based local-tld workaround into the README, though it probally belongs somewhere else, if it is kept. sry ^^
