There is a increment_version.pl, which uses the incversions.txt
to increment the CLI version numbers.

But it first checks that there are new published UNO types,
and exits if there are none. Not sure where the input for that
is supposed to come from.

But the OOo docs claim that all version numbers have to be
incresed for every release to work around some MSI issue,
so change the script to do that and add an incversion.txt
in unoil too.
