[equinox-dev] new provisioning console commands

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

I added some stuff to the provisioning
console.  See the help for details.  Basically there were two
changes.
- new "provlg" (list groups)
command. This lists all the "group IU" (that is IUs that have
the group capability).  I'm not completely happy with this setup (there
could be lots of capabilities of interest) but groups seem particularly
of interest for installing etc.  This dovetails nicely with the new
feature->group metadata generator...

- several of the list commands now allow
for filtering by taking an optional IU id and version *range*.  For
example:
        provliu
* * [3.3, 4.0)   = list all IUs in all metadata repos that have version
3.3 (inclusive) upto 4.0 (not inclusive)
        provlp
this org.eclipse.foo 1.0   = list all org.eclipse.foo IUs in this
profile that have version 1.0 or greater

The version range syntax is a bit of
a bummer as 1.0 => 1.0 to infinity not 1.0 exactly (which would be [1.0,
1.0]).  We can work on this for ease of use.
