Option to automatically parse quoted input

There is currently no parsing for input with quotes. For example, given `/command "This should be one argument"`, the `CommandExecutionContext` args look like `["This, should, be, one, argument"]`. Ideally, there would be an option in the command manager to pre-process arguments and group quoted one. In my example, this would resolve to a single arg, `[This should be one argument]`. This would be a solution to #253.

To expand on this, nested quotes could be escaped with `\`. Additionally, the method to set this behavior could take in a boolean to denote whether or not the quotes should remain in the parsed arguments.
