Propose that feature be implemented for allowing/restricting editing of issues, posts, etc. with a timer.

This feature will be of particular use on Redmine.org because at the moment, if we submit an issue, we are not allowed to go back and edit it at all.
This makes sense because you do not want the content of what people are responding to and working towards to change, but it always makes it very difficult to correct mistakes or to add in missing content.
This issue could potentially be solved by implementing a way to allow editing based on a timer.

If the timer is set so that you are allowed to edit only your own things and up to 1 hour later, then we would be able to go back and make changes as needed within an hour since creation.
