Assorted cleanups and fixes.

* Clean up spacing/indentation
* Proper enum formatting
* Fix nano dismissal (for real this time)
* Do not copy Player struct when a pointer is right there
* Stop looking after the trade partner has been found
* Make sure we're shifting unsigned values (and 64-bit when they need to be)
* Look for JSONs in tdata/
* Add a dbsaveinterval to the example config.ini, in the login category
