Description
There are a lot of internal components to dartdoc that import big namespaces like package:dartdoc/dartdoc.dart and package:dartdoc/src/model.dart, even though they don't need the full import tree (or could be changed slightly to avoid it). This means that the grinder is indirectly importing package:dartdoc/lib/src/templates.renderers.dart and it makes it impossible to use grind build to regenerate the file to accomodate changes that result in errors. This is most noticeable now after #2564 has landed.
It's only a modest inconvenience to run the builder by hand, but it is still an inconvenience.
