SSH access from the Sites page; containers and discovery dialog; dialogs fit small screens

Each site has an SSH button: it opens a TCP port on an edge whose target is
Bamboo's built-in SSH server, and shows the ssh command to use. An end-to-end
test signs in through the edge, the tunnel and Bamboo's server.

The Found by dialog now lists Docker containers and discovered services, wraps
long names and groups TCP and UDP ports. The dialog overlay no longer lets a
wide table push a dialog off a phone screen. Builds against Bamboo v0.1.8.
