Since we already have the KUN placeholder, there's no need for this {STRING 5} stuff.
Also, it makes it easier to delete all the {KUN}s in hacks later on if desired.
This descrepency was causing a lot of annoyance when using porymap, because porymap generated the ids in map_groups.h from the name, and mapjson was generating map_groups.h from the id in the json files. So just name them the same already like every other map in the repo.
The contest scripts actually use addvar to add a -1 to a variable instead of using subvar to subtract a positive number. This is fine in vanilla, where addvar script command does NOT support adding the value of a variable to another variable (like subvar supports), but should anyone want to change it, contests will be inexplicably broken.
The nops are essential to the hidemoneybox and updatemoneybox commands when using vanilla versions of those commands. Even though they're not actually used parameters in the command implementation, they are still consumed, which means if someone were to get rid of the nops (as I did in TriHard) it causes the commands to consume bytecode that are not theirs, resulting in undefined behavior usually leading to softlocks. Folding the extra bytes into the macros means there's no chance of the extra bytes getting losts in scripts.
Renaming the command to something that makes more sense as to what the command actually does. The command copies the current xy of the instantiated object back to its template, so that the object remains in the same place if the player walks away and despawns the object, and then comes back. "moveobjectoffscreen" implies that it might be taking the object and moving it physically to an off-screen location somehow.
