These exceptions are almost always caused by a legitimate user
error (e.g. a nonexistent repository), and as such shouldn't be
reported as an unexpected error with the suggestion to use "pub
--trace".

Previously, pub would exit immediately after the first load error was
reported. Now it will wait to see if any other transformers have
errors and report those as well.

This change does three things:
* Splits out a WrappedException class from ApplicationException.
* Uses fail() pervasively rather than new ApplicationException() everywhere.
* Moves exception classes from utils.dart to exceptions.dart.
