Added list of sha1 revisions that should never be cherry-picked to the release.

This list can be read by a script and thus allows for semi-automatic cherry-picking.
Revert "Use method leafGridView instead of old leafView"

This is related to flyspray issue #1390. While there is a fix
for it in master, we refuse to cherry-pick it to the release as
it might severely break backwards compatibility.
This patch reverts commit b09888be847123d0955cc5e922ccbc772abde7bc and
test_geogrid runs smoothly now.
[bugfix,release] Do not try to add flags before adding the executable.
