Title: Make the vibe.d dependency optional.

Just a little cleanup. I didn't see this at first, but `Have_vibe_d` is defined automatically by DUB, so there is no need to define it manually. Also, the `vibe-d` dependency is now optional and there is no need to force the library to be a "sourceLibrary".
