Throw a more user friendly error when capitals exist in command parameters or convert to lowercase.

Feature

Right now, if you try using capital characters in your command parameters, you get a cryptic Discord API error. Either convert to lowercase or throw a user friendly error.

Ideal solution or implementation

An ideal solution is to simply throw a more user friendly error, eg:

error: Capital characters are illegal in command parameters.

Alternative solutions or implementations

An alternative solution could be to simply convert command parameters to lowercase automagically to prevent the error altogether.
