This level is not printed by default, but will be printed by pub if --verbose is set. Also update the observe/polymer version constraints. This change is backwards-compatible from a transformer implementer's perspective, so the lower bound doesn't need to be incremented.

Barback is an asset build system. It is the library underlying
pub's asset transformers in pub build and
pub serve.
Given a set of input files and a set of transformations (think compilers, preprocessors and the like), it will automatically apply the appropriate transforms and generate output files. When inputs are modified, it automatically runs the transforms that are affected.
