[equinox-dev] system properties renamed

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

In an effort to make things more consistent
we have renamed most/all of the system properties that are currently used
to manage the running of the agent to be of the form "eclipse.prov.*".
 I committed changes across the code base and the three base launch
configurations and it all appears to work for me.  Please let me know
if there are any issues.

Sidenote:  For the most part this
use of system properties will have to go away in favour of a more realistic
configuration mechanism but for now this form is reasonably convenient
and functional.
