Migrate AttrValidator to nested error format; modify generator logic in ErrorCollector.

Browse Source 
AttrValidator's changes are fairly self-explanatory, but ErrorCollector's
changes are worth a little discussion.  ErrorCollector can use generators at
various points during its flow control; there are two distinct generators that
it should use: 1. The one used for the output, and 2. The one used for the
error output.  These will usually be the same, but in the odd case where they
need to be different, getHTMLFormatted() will accept an alterate configuration
object with an appropriate doctype.
