Inputless command fields should optionally take boolean inputs

[baite1]

- playsound's (custom) field (and any other command's inputless fields ) should optionally take a boolean as an input
- push, for example, requires 16 if statements to check for its (force_along), (no_rotate), (no_damage) and (ignore_collision) inputs, and 16 similar lines to execute the command itself

why?
other command fields can take booleans, but these could just require the name alone for backwards compatibility

else if (!scriptEntry.hasObject("custom")
        && arg.matches("custom")) {
    scriptEntry.addObject("custom", new ElementTag(true));
}

would become

else if (!scriptEntry.hasObject("custom") {
    if (arg.matches("custom")) {
        scriptEntry.addObject("custom", new ElementTag(true));
    }
    else if (arg.matchesPrefix("custom")
            %% arg.matchesBoolean()) {
        scriptEntry.addObject("custom", arg.asElement());
    }
}

this would have to be changed in the following commands:

• cooldown (global)
• adjustblock (no_physics)
• webget (hide_failure)
• age (lock)
• attach (relative) (sync_server) (no_rotate)
• cast (remove) (no_ambient) (hide_particles) (no_icon)
• fly (cancel)
• follow (allow_wander) (no_teleport)
• health (heal)
• leash (cancel)
• mount (cancel)
• push (force_along) (no_rotate) (no_damage) (ignore_collision)
• rename (per_player) (list_name_only)
• rotate (cancel)
• shoot (no_rotate)
• spawn (persistent)
• walk (auto_range)
• fakeitem (player_only)
• give (unlimit_stack_size)
• lookclose (realistic)
• actionbar (per_player)
• blockcrack (stack)
• experience (level)
• narrate (per_player)
• sidebar (per_player)
• title (per_player)
• execute (silent)
• copyblock (remove_original)
• explode (fire) (breakblocks)
• firework (flicker) (trail)
• modifyblock (delayed)
• playsound (custom)
• schematic (delayed) (entities) (flags)
• strike (no_damage)
• switch (no_physics)
• time (freeze)
• worldborder (reset)
• filecopy (overwrite)
• determine (passively)
• inject (instantly)
• wait (system)
• worldedit (undoable) (noair)
• discordmessage (no_mention)
