Update our Oomph setup to use m2e 1.14.0 from their milestone
update site. Unfortunately we need to use the milestone since
the fix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=548652
has not yet made it into a stable m2e release.

Closes gh-19280

Change the Oomph setup to no longer hide nested Maven projects
so that https://bugs.eclipse.org/bugs/show_bug.cgi?id=553789
doesn't get triggered.
