Added typeNameOf, which is a safe way to get the name of a DartType,
even when the type is a FunctionType, which has a null name in newer
versions of the Dart analyzer.

Added LibraryReader.pathToUrl(Uri|String), which computes the import or
export path necessary to reach the provided URL from the current library.
Also added pathToAsset and pathToElement as convenience functions.

Expanded package:build support to allow version 0.12.0.
