After this change, a Milestone name can be changed quickly from its Workboard,
with all the expected validations of course:
| Before | After |
|-----------|-----------|
| {F253460} | {F253462} |
Before this change, people able to edit a Milestone had to do so much
steps to exactly do the same thing:
1. click on the Milestone name
2. click on Manage
3. click on Edit Details
4. change the name
5. Save
Thanks to this new shortcut, this is no longer necessary.
This does not change the level of permissions needed: if you have not enough
permissions to see or edit a Milestone, you cannot access this feature indeed.
