The `devjson` command needs to ability to handle overloads. With this change, if a method is an overloaded method, the command will get all methods on an object that match the entered method name, then get the first entry in the list of methods that matches the length of the provided parameters list.
This won't work in all cases, as there may be situations where the parameters of the methods have the same length, but different types. In that situation, it's likely that the conversion from `Object` to the desired type will fail, in which case, the command will notify the user that something went wrong.
