Improving the help command

[ceruzaa]

Currently the help command ends up being quite verbose. This needs to be improved.

Instead of writing out the help strings from all commands when using "Dave help", it should print out a comma separated string with all the available commands. The user should then be able to type "Dave help command" to get the detailed information about the command.

Getting a full string should still be possible by typing "Dave help all". This might get restricted to private conversations with Dave, need @DriesVuylsteke to give input on that.

Part of this refactoring should be distinguishing between commands that can be run by regular users and commands that only can be run by administrators.

Instead of forcing people to pm Dave, we could just have pm the person. So you still do the command in the ROAP channel or privately to dave, it doesn't matter. Dave replies in pm whenever the message is longer than a certain amount of characters. Thoughts about this solution @ceruzaa ?

@DriesVuylsteke I think Dave replying in pm is a good idea, but I think a setting a character limit may be the wrong way to go. Maybe instead, we should just decide ahead of time that something will be too long and that it should be sent via PM instead. If we do a character limit, we might accidentally cause commands like help to be inconsistent due to the length of the help message for the command, you either want all responses from Dave to be shown in pm or in the channel so that the users know what to expect.

For example, in this case, the "Dave help all" will reply in PM, and dave help / dave help command will still be displayed in chat.
