KDocTools history import

[Alex Merry]

I screwed up the history import of the FindDocBook*.cmake files from
e-c-m into KDocTools, so Luigi asked me to do it again.  This involves
removing those files, then merging in a more sensible history (that
isn't curtailed like the other one was).

This can be found at
git at git.kde.org:clones/kdoctools/alexmerry/hist-import
(kde:clones/kdoctools/alexmerry/hist-import will work once the anongit
mirrors pick it up).

I've documented the magic I used at
http://community.kde.org/User:Randomguy3
for those who are interested.

Can people have a look and check that the history seems sensible?
