How should I submit these in the future/patches?

You should create account on GitHub, browse and edit source file directly in vibe.d repository, fork and create pull request. This is possible via GitHub web interface. Look for "edit" and "pull request" buttons.

do I get my project to use the cutting edge with dub?

Try "dub upgrade" command.
