git repos: partial history rewrite

[Harald Sitter]

Because I can't read I screwed up some of the application repos
yesterday with a bogus merge of kubuntu_unstable into the
kubuntu_vivid_archive branch.

To avoid insanely mad merge and revert piles I decide to do a partial
history rewrite.

WHEN USING ONE OF THE FOLLOWING REPOS, RUN `git pull --rebase` FIRST
on both kubuntu_vivid_archive and kubuntu_unstable (assuming you have
latter checked out).

For the new applications release they also will want uploads as they
most definitely will not build with the original upload.

Additionally the following repositories might see a rewrite later
today (they have a slightly more complicated history):
kalgebra
kate
analitza
parley
libkeduvocdocument
khangman
print-manager
konsole

The following repositories should be fine with unstable being merged
as there was not impactful delta:
analitza
kanagram
kapptemplate
kig
okteta
gwenview
cantor

Sorry for the inconvenience.
