DreamStudio's API Key is not retained and has to be inserted at every StableStudio session

[Harvester62]

Describe the bug The Dream Studio API Key is not retained after closing the program, therefore at the next restart it has to be inserted again.

To Reproduce Steps to reproduce the behavior: See above

Expected behavior It would be convenient if the API Key, once inserted as required, could be someway stored locally, better if inside a separate, dedicated file so that the user might eventually, for any reasons, be able to delete it.
