pharoRepository backend pullFrom: pharoRepository origin.

Take into account this particular two lines can break your working copy if
you have uncommited changes.

> pharoRepository push.
> pharoRepository checkoutBranch: (SystemVersion current commitHash).

> [(pharoRepository savedPackages select: [:aPackage | aPackage isLoaded
> and: [ aPackage  isModified ]]) do: #reload ] on: MCMergeOrLoadWarning do:

And this is a patch because bootstrapped images have 3 dirty packages. We
should just fix the issue instead of patching it.

In any case, I vote to put this in the Pharo plugin in iceberg.
