* Still lacks dates and correct Unicode string handling
* Re-add, per Brion's request.
* Add an easy PHP tester, to run the tests used for the native parser.
* Update to pass 20 tests out of 27. Still to go:
** Implement dates.
** Fix order of operations.
** Fix backslash parsing.
** Implement if-then-else and ternery operator.
* Reimplement tools, starting with a spiffy AJAX expression tester. Didn't bother implementing as non-AJAX, as it's just an extra.
* Change exchange protocol between native parser and PHP app. Resulted in 2-3-fold performance boost.
* Fix minor bug from last night.
* Introduce a syntax check on-save.
* Introduce filter history (requires DB schema change).
* Deprecate now non-working /tools interface (will come back).
* Revert r38187 for now:
** Introduced a memory leak.

* Integrate with the PHP abuse filter using AbuseFilterParserNative class.
* Fix memory leak.
