v0.3.0-beta.3

This release addresses some important bug fixes, including a performance regression. It also sports a complete reimplementation of trim, utilizing the possibilities of the data structures of the new evaluator.

cue trim

The biggest new feature of trim is that definitions now can remove fields of non-definitions. Other than that, it mostly is just bug fixes. The data structures of the new evaluator make it considerably easier to implement, leaving less than a quarter of the code.

encoding/protobuf

This package now links in the full set of builtins, obviating the need for API users to have to do this.
