Support more third-party account connections

"We do not have plans to add any additional 3rd party connections at this time. If you have suggestions on one to add, post a discussion on the fluxer github please!" - Lilith.

Based on what one Fluxer staff had said, third-party connections are not planned to be added. As such, I decided to leave this disscusion remain open in case there is a need to add this feature in the future.
