Fwd: Really usability fix for Versionner

Hi

I checked with christophe and it is IMPOSSIBLE to use Versionner for 
managing projects like SciSmalltalk.
First I cannot even reach the ok or cancel button (check the png - this 
is not fun)
Second and more important, Metacello gives warning on projects I do not 
have any control.
So based on the feedback of Christophe I introduced a setting to 
disable/enable the check.

It is important to have it in Pharo 50 else we will not be able to use 
Versionner or we will have load this fix each time we want to manage 
large project and I'm fed to spend my life updating configuration of 
more than 30 packages by hand. Versionner is cool but without this fix 
the system kills my productivity.
I do not have much time to improve Sci and I would like to prefer to use 
it on real issues
and not just spending time updating stupidly numbers.
