[Tracker] Updated GUI

[jamie <jamiemcc blueyonder co uk>]

Have now updated the GUI to use a sidebar instead of tabs

There are still a few things left to do before releasing 0.6 :

1) Get all the other services in t-s-t (chat logs, attachments and
applications)

2) Fix the metadata tile to display metadata for emails as well as the
missing services in (1)

3) make all calls async in t-s-t

4) a few of the remaining bugs in bugzilla for t-s-t

5) show everything in a service at starup or when search term field is
blank

anyway almost there - expect a release probably saturday or sunday at
the latest

Feel free to start testing it...
