vagrant/README: fix a `screen` command
Merge pull request #120 from pkit/rest

correctly pass request payload to any type of job
implement all REST services

all REST srvice endpoints are implemented
you can HEAD, GET, POST, PUT and DELETE
although you cannot delete objects in Swift as a result of a DELETE, but you can do any other "RESTful" thing there
fixed the following:
- better precedense of headers, usually needed for HEAD, which should sometimes output same headers as GET but with no body
- status handling, `message/cgi` and `message/http` responses should be able to overwrite HTTP status

and as a consequence you can now shoot yourself in the foot by using `Content-Length` with no content and other strange constructs
