Add option to select all modifications by default
Created originally on Bitbucket by mrh1997
When doing any modifications currently all modified files have to be selected in the "*" column (either manually or by clicking the "All" button).
It would be very helpful if this behaviour could be inverted by an option. That means (if the option is activated in mercurial.ini) by default all changes are selected and the user manually has to deselect (or click "None" button).
