Fix Command Parsing and Config Loader

So apparently the config reload was never working cause we never reloaded the plugin instance's config. Oops.

Command is now parsed to consider things within double quotes as a single argument.
To use double quotes, use \" for escaping quotes.
To escape the escape character use \\.

Updated API versions.
