BZ 1142108 - fix NPE - in case someone deleted jboss.bind.address.management from rhq-server.properties
[1071379] CTRL+C doesn't shutdown server when running in console mode on Windows
Rhqctl was actually the program running in the foreground
when the 'rhqctl console --server' command was issued. The JSW and Server
processes were also running, but in the background.  When issuing a
CTRL-C it was actually rhqctl that was getting interrupted and killed. The
CTRL-C was not reaching the wrapper, or the server.  This got a little
infuriating because even if you manually killed the Server, the wrapper
would detect the "crasg" and then spin up a new server process :)  So, to
recover you needed to manually kill the wrapper.exe process, and then
manually kill the RHQ Server process.

With the fix we now launch a new cmd window for the Server (asynchronously,
via the Windows start command) which allows rhqctl to complete and exit.
The wrapper is now running in the foreground of the new window, and CTRL-C
is handled as expected by JSW (shutdown), as is double CTRL-C (immediate
shutdown).

Analogous work done for --storage.  Note that we don't support 'rhqctl
console --agent' and already direct users to run rhq-agent.bat directly.
[1064332] Horizontal size of the dashboard's left panel gets stuck after changing verticle panel size
When we removed the borders from the dash columns it made it very difficult
to grab anything for horizontal (i.e. width) resize.  There was only a
small, invisible area at the '+' shaped intersections of portlets.

Add back a 1px border, but make it transparent to keep the patternfly l+f.
Although the border can't be see, now when hovering over the border the
resize icon appears more readily.
[1043099] Add new autogroup chart to dashboard shows empty chart in dashboard
Disable the ability to add Autogroup or Autocluster metric graphs to the
dashboard.  It doesn't work because the portlets don't support them, and
these types of implicit groups should not be referenced outside of their
Tree navigation context. Despite being persisted they are maintained only
at click-time.
