Changes

Causes seperated party characters that have previously been [[FF7/Field/Script/Opcodes/09 SPLIT|SPLIT]] onto the field, to be joined back together again; that is, only the party leader becomes visible on the walkmeshfield. This should be called if a previous SPLIT has completed (the party members have finished speaking, or performing their actions, for example). As with SPLIT, the speed of the join is specified, from a scale of 1 (almost instant) to FF (very slow walk).
