Core command output classes

[ZeroKnight]

Need some small dataclasses encapsulating core command output that will be passed to core_command_* callbacks.

• [x] CommandHelp
• [x] VersionInfo

CommandHelp

Encapsulates the end result of a command help request, such as:

• The command or module name that the help is about
• The command or module description
• The usage line for the command
• The help strings for each option/argument
• Dict of CommandHelp objects for any subcommands
• Whether the command or module exists (other attributes except name should be None)

This will shift the burden of performing all the string manipulation on the result of format_help() from the core_command_help callback in protocol modules over to Core.

VersionInfo

Provides current version, release date, and anything else version-related appropriate to ZeroBot. This will likely get more attributes in the future.
