for core commiters: version.txt

for core commiters: version.txt


Hi devs,
for anyone commiting to core: The version in version.txt must always
be reflecting the current state of trunk. If it says "1.2.6" the trunk
revision must be the same as the one tagged as 1.2.6. Upon the first
commit thereafter, version.txt must be updated, eg. to 1.2.7pre. If it
is unclear whether the next release will be a point release or not,
just change it to 1.2.6post.
I guess there could be a better naming convention than appending "pre"
and "post", but the important thing is to have it there.
Thanks
Jörn
