Set default svn module to branch for feature branch

Set the default SVN module location to the name of the branch.  This was
causing a configuration issue when a feature branch project was created.
Now the feature branch project will check out the "name" to the
workspace and reference it as it's module.
Fixed a bug using promotion plugin and svnmerge

When using the promotion plugin to perform an upstream integration, the
svn information is not found.  This is due to it not being copied to the
promotion sub-build.  As a quick fix, if the upstream is not found, try
to retrieve it from the root build.  Else it will fail as before.
fixed SVN rebase/integration issues

Found multiple issues with integration/rebase.  This was mainly due to
the reintegration of the upstream back into the branch.  I found
documentation in svnbook that showed the option that was not advised, is
actually advised.
