VGV952CJW33-E-IR: Provide a branch update script.

It's hard to follow this branch by using "git pull",
since it would merge all changes together.
I use the rebase method to lower the maintenance effort.
Since the branch is pushed to github via "git push -f" the
history is completly rewritten on github.

The script updateGitRepo.sh creates a test branch, changes to it
and removes the current branch. Then it checks out the
development branch from origin and switches to it.

updateGitRepo.sh
