sse working, but blocks all further connections! :(
OH SHIT WHAT EVIL HAVE I DONE?
call Celluloid.sleep instead of Kernel#sleep
Merge branch 'nocon' into sse

Conflicts:

handle ioerror for closed eventsources also
split stashes for ws/sse, add event/msg helpers
fix tests, remove unused #params from ws responder

also forward instance to class methods on base, instead of call
add eventsource route builder, tests, readme bits
more readme bits, make Stash#each return nil
