Open showroute with last stored database from updates.php

[michihdeu]

https://travelmapping.net/devel/updates.php features the 'File Root' column. A new (automatically added by frontend) column could open showroute with dbname=TMxxxxxx where xxxxxx is the last stored alternate database before the date indicated in the 'Date' column. That means, with highway data and user data from the day (or week, or month or year) before the update was made.

It would be nice to have the option to directly switch to mapview with the current view.
