add last version
add websocket support to /container/<name>/attach/ws

This function add the possibility to attach containers streams to a
websocket. When a websocket is asked the request is upgraded to this
protocol..
change tag -> repo name in build usage
use http://get.docker.io/latest
put the websocket route in the map containing all routes

Instead of handling the websocket differently just handle it as a normal
route and upgrade it to a websocket.
useless type
useless function. forgot to remove it.
reuse the type
docker.upstart: avoid spawning a `sh` process

start script / end script create an intermediate sh process.
docker.upstart: use the same start/stop events as sshd

Is probably more solid
add server.ContainerTop, server.poolAdd and ser.poolRemove tests
Add CompareConfig test
prevent any kind of operation simultaneously
add Volumes and VolumesFrom to CompareConfig
add VolumesFrom to MergeConfig, and test
+ Runtime: inject dockerinit at /.dockerinit instead of overwriting /sbin/init. This makes it possible to run /sbin/init inside a container.
Merge branch 'master' into add_last_version-feature
handle -dev
add ps args to docker top
bump api version to 1.4
