Shell Rewrite + Better Commands + Command Argument Parsing

[Sh-wayz]

Shell Rewrite

Shell Features

• If debug_mode is enabled in the server.yml, not recognized commands should be evaluated as python.
• Maybe an option for custom shell prompts to get rid of the boring >. _{you can also use colors!}
• The shell should also handle the up arrow correctly like any sane shell.
• Fix all arrow-key handling.
• vi_mode.
• save history to file.

Command / Command Parsing Features

Note: For more information on commands, see here: https://wiki.vg/Command_Data

• Aliases for commands.
• A help command which can grab the docstring of commands added by plugins.
  • It should also display the args for the command(and type if the command has typehinting)
• A send() coroutine passed to the command which handles responding to the respective player and/or the console.
• A proper object model instead of a uuid passed to the command.
• Parser which parses different types for commands, based on the typehints/annotations from func.__annotations__
• Add ability to add custom parsers.
• Support most parsers in the below checklist.
• Parsers should be structured into classes for ease of use.
• Optional: syntax highlighting.
