All long labels have been removed as the bridge list interface and
discovery interface was reworked. Discovery of new lights happens
automatically and bridges are refereshed when changes happen.
This patch will allow lights that have not yet been added to a
group to be manipulated on their own, potentially opening up for
support for adding lights to groups from the ui.
This patch intruduces more robust handling of situations where
a bridge can not be discovered by means of UPnP.
A modal now pops up, which allows you to manually enter an
ipaddress if no bridge can be discovered.
