More work on faster traversals, and fixed support for actually returning nulls when nothing is found
Tracking for explicit nulls
Added support for other helpful methods that autobeans use. Not quite as efficient as it could be, still readonly
Tests for beans in both autobeans and gso. This may break external json files that are used in those tests
Gutted consumeString to have it not validate the string as it walks it, but only find the end, leaving it up to asString() or matches() to do the unicode and escape junk
