Support file versioning
The purpose of this feature is to aid communication between the planner/controller and help ensure that the maps printed by a printer and the control descriptions are consistent.
A file version field will be defined.
It should be possible to include this on the maps as special text item and configure for it to be include don the control descriptions.
When saving the file if it has changed and a version number field is displayed a prompt should be offered to remind the user they may wish to update the version number.
Optionally a comment could be added with the version. It may be possible to auto-generate a version of this indicating what has changed.
