Forced updates of rtt/ocl 1.x branches on github

Today, there have been two forced updates of the rtt/ocl 1.x lines on github,
since they contained commits (2 for rtt-1.0-svn-patches, 1 for ocl-1.0-svn)
not being present in svn.

You'll better do the pull on a 'testing' branch to see if anything gets broken
in case you built on these wrong commits.
