We need to think about releases now. Currently everyone just uses master and hopes nothing breaks. We try to ensure stability with every change, but sometimes things slip through.

My proposal:

• Release version 0.11.0, incrementing the current working version number (0.10.0)
• Generally adopt semantic versioning
• Distribute DLLs with releases
• Aim for stabilizing into 1.0 soon

This will help us meaningfully communicate API changes, allow bindings to clearly state which versions they support, possibly backport relevant fixes, and give us a place to distribute official DDL builds.

This is based on @dandeto's proposal in #700.
