All this tracklog stuff bring up a fairly serious issue that tracklogs
cannot be edited.

I think we need, at a bare minimum:
* Deletion of tracklogs by admins
* Editing for track logs (to remove "noisy" tracks we know are not
good, such as when you drove into the store)
* Editing of tags on tracklogs (I would also like to see them
seperated by commas, to allow tagging such British Columbia or South

After that, we migth want to consider whether or not to tag tracklogs
as trusted or not.
