Status of replacement of svn:externals

[Cantor, Scott]

I've done all the main projects for V3 plus the testbed and just copied in
the parent project settings files.

The svn:externals step of the project create scripts was removed.

My suggestion is to create something similar to the resources/eclipse
directory in the parent-v3 project and replicate that in the
opensaml-parent and idp-parent modules so that we can maintain distinct
copies at the project level, which will be the most common need.

Actually syncing up copies is easy of course, with xargs, but that won't
do a specific merge. They are all properties files, so I don't think it
would be that hard to cook up a script to chop out an existing line from a
target file and add a specific property back to the end if we need
something mechanical. I would note that the existing prefs files can't be
intelligently maintained with the GUI from within the parent project(s)
anyway, since Eclipse doesn't see them.
