No longer log commands twice

[CommandMC]

• getLegendaryOrGogdlCommand and its variants are no longer exposed/no longer exist
• A new purpose attribute was added to runLegendaryOrGogdlCommand's options, which makes it possible to define what the command we're running is supposed to do
• Instances of the "getCommand, log it with custom message, runCommand" workflow have been converted to using purpose

I think this is a good compromise between being verbose on what we're doing vs avoiding log spam

I don't know if we need the purpose attribute. I will see tomorrow how i would implement it. Maybe i miss something and we need the purpose, but i want todo it with less arguments
