Help command is incomplete

[Ricket]

The help command is incomplete.

Proposed fix: Redesign it so that the help command is a global feature, and each script should have some help data in the script which the help command reads from the scripts. This will mean less maintenance, and disabled scripts will not show up in the help command.

Perhaps the "listen" function can have an additional parameter which is the description of that command or feature.

@Ricket: I think the plugins should be more modular, so you can put in a descriptions and stuff, so the help just pulls the info "magically". Check out this implementation: https://github.com/stenehall/bot.js
