Aidan MacDonald d5a081cbd1 gui: Remove "enum list_wrap" from list action functions
Removing the "list_wrap" argument is actually pretty easy.
In practice, almost all lists are using LIST_WRAP_UNLESS_HELD
behavior so we can make that the default. A couple of lists
disable wraparound with LIST_WRAP_OFF; this is now achieved
by setting the list "wraparound" flag to false when setting
up the list. LIST_WRAP_ON was unused and is of questionable
value, so it has been removed entirely.

This makes list wraparound behavior a property of the list,
controlled solely by the "wraparound" flag. The result is a
simpler list API and implementation, without changing the
behavior of any lists.
