[3.1.1] Land vs's HTMLPurifier_Generator patch, and a number of other bugfixes for that change

- Convert a number of calls to use new constructor signature for Generator
- Make generator require configuration; this exposes a number of latent bugs
- Removed generator hack
- Convert Printers to use new optimized ConfigSchema format
- Hack with Printer configuration; pass an array(generator config, render config) to distinguish between output and target.
- HTML/CSS Printers need to be primed, otherwise fatal errors
- Convert a few test-cases to use member properties
