Summary: Editor should discard parse errors

Initial Comment:
The editor chokes on source files containing something like the following:

@Foo class Bar {
}

The file can't be saved or opened.  That's unfortunate, since a very natural place to put an annotation is in front of a class declaration.

The search for a package declaration is stymied by the presence of an annotation, which the parser doesn't support; our handling of the error (and any other tokenizing errors that might occur, unless we wish to assert that no parse errors will *ever* occur...) should be made more elegant.
