OptionalArg don't support collections types

[creatorfromhell]

This is a suggestion to change what class file LiteCommands looks for when it comes to collections. I think instead of checking for a suggestion on List.class, it should instead check the class of the objects the List contains. Example List should look for completion based on GameMode.class not List.class.

This is how it currently works only indirectly to be able to better manage suggestions. LiteCommands -> List suggester -> GameMode suggester

Currently, when providing for the class type of the object in the collection, and not providing for the collection class results in an error. As an example, I changed to using ArgumentKey as suggested in #377 and it errors out when it gets to the List argument.

I cannot reproduce this issue. You can see how use List<T> arguments in the following example
When I use list arguments, everything works normally. Maybe this is a problem with the use of @OptionalArg ? Try use @Arg (a collection can be empty)

Seems to be the case with OptionalArg throwing the error.
