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.
* adds some constants for standard script names and messagebox types
* replaces some callstd calls with msgbox calls where equivalent
* replaces msgbox and callstd calls using raw digits with versions that use the constants
