Sync script commands

[GriffinRichards]

• Use the single-line comparison script syntax (e.g. goto_if_eq VAR, value, Script)
• Drop a number of optional arguments from script commands, including the 'no warp id' indicator from warp commands.
• Allow specifying the name of the string var for script commands that write to string vars.
• Add constants for the textcolor command
• Sync scrcmd.c with pokeemerald
• Sync macro comments and argument names with pokeemerald, and add new comments
• Add missing supplemental macros from pokeemerald
• Sync script command function and macro names with pokeemerald. The following are all the renamed macros:
