suggestion: Base versioning off of Sway's

[markstos]

The idea is to include the Sway revision last forked from in the version number to help people understand better what features to expect in total.

For example, the current version is 0.4 and based on Sway 1.9. The next release will be based on Sway 1.10.

A schema like Ubuntu uses could include both the upstream version and the SwayFX version:

1.10-swayfx-0.4

That would be SwayFx 0.4 features based on Sway 1.10.

1.10-swayfx-0.5

Would represent a future release of SwayFx adding new features on top of Sway 1.10.

I'd been considering how we could better handle versioning. I think this is a good idea! Thanks :)
