1.13.6 (unstable):

* Python scripts:
 - Fields value may now be changed like so:
   record["fieldname"] = 123
 - Simple navigation is posible via, for instance:
   ui.show_table_list("artists")
   ui.show_table_details("artists", 10)
   where 10 is the value of the primary key in the table.

* Avoid showing %20 in the window title.
