Alert user when file unlocked behind their back
The CLI now correctly detects if a file that should be locked because it is marked lockable and is in an active changelist has been unlocked behind the users back on the server. However, we do not alert the user in any way or fix up the situation in the local cache.
- Decide if the the local lock cache should be automatically fixed up or whether it should require a "validate locks"
- Notify the user at appropriate points.
