Problem: Project structure out of date
Solution: Regenerate with latest zproject
Problem: No API model for generating language bindings
Solution: Add api/drops.xml and autogenerate QML bindings
Problem: Autogenerated QML bindings are barebones, not idiomatic
Solution: Add hand-written idiomatic wrapper for `QmlDrops` => `Drops { ... }`
Merge pull request #30 from jemc/master

Problem: No in-repository QML bindings
