bpel support in beta3

[ant elder <an...@gmail.com>]

I've spent hours last night trying to get the helloworld-bpel sample
in beta3 working but without success, so now i've removed the sample
from the beta3 branch.

At some point (before 2.0?) I think we should consider if we want to
move the bpel extension out of trunk to contrib until someone has the
inclination to get it going well, but i'll leave that discussion for
now and just take the broken sample out of beta3.
