app.home and idp.home when running the testbed inside eclipse.

[Rod Widdowson]

(Probably for Tom).

When running inside eclipse, where are app.home and idp.home set up from?  I
see that they are being set, but I cannot see where from.

The issue I am running into is the usual one on Windows - that prepending
"file://" to a path which starts with a "Dos Device Name" (e.g. C:/) doesn't
work because you end up with what looks like a network URL and badness
ensues (because java cannot find the host named 'C').   The solution to this
is always to just set the variable correctly (strip the device name, add a
preceding /, or use the real path), but to do that one needs to know where
to make the change.

I can see where this is done for running from MVN, but thusfar I cannot see
it for eclipse.  For now I force the issue in idp-testbed-logback-launch so
I'm not blocked, but I'm curious to see where it is set...

Thanks
