title: Egit: configure rebase as default pull strategy for master branch
body: <p>In our new project we've got 10 repositories, each of which have interdependent Eclipse projects.</p>
  
  <p>I plan to establish a default workflow, where each developer is working on the master branch and uses the commit-pull-push cycle. To reduce commits and get a nice linear history I prefer rebase as standard strategy for pull. This works fine, if <code>branch.master.rebase=true</code> is set. </p>
  
  <p>Unfortunatelly it has to be set manually for all repositories, after they are cloned with EGit. I tried setting <code>branch.autosetuprebase=always</code>, but this affects manually created local branches only, not the master branch after a clone.</p>
  
  <p>I would like to automatize the initial setting of <code>branch.master.rebase=true</code> to reduce errors and for convenience. Is there a way to do it? Preferably inside of Eclipse/Egit, but other ideas are welcome, too. </p>
