Before you had to type <prefix>help netload to get information about
netmodules, but now it is netmodules to not conflict with a command with
the same name.
Now you can specify what command you want help on.
Respond if no specific command or help
Add moreHelp for the userinfo command
Use regex to replace <prefix> with actual prefix
* Remove unused dependencies
* Add basic downloading of modules
* Add valid-url as dependency
* Add loading/reloading of netmodules
* Add support for help on netmodules
* Add whitelist for netmodules
Pass objects instead of using a switch statement.
Now I don't have to restart the bot whenever I add a new command
that needs specific arguments other than 'message'.
