Allow editing of saved queues

[TCHalogen]

Overview Queues that are created and saved have no capability of being edited within the game's interface. The only way to do so is through the undocumented method of copying the queue, which sends a JSON object of song IDs and a name to the clipboard, and pasting it to a notepad — leaving users with information that may be too technical to understand.

Desired Solution Given that a JSON object can be produced with the corresponding song IDs and queue name, it would seem that there shouldn't be issues with parsing through whatever is saved and repopulating the queue list.

The details listed in GitHub issue #11 would need to take precedence here, as there's also no way to edit individual songs within an existing queue.
