[3.1.1] Memory optimizations for ConfigSchema. Changes include:

- Elimination of ConfigDef and subclasses in favor of stdclass. Most property names stay the same
- Added benchmark script for ConfigSchema
- Types are internally handled as magic integers. Use HTMLPurifier_VarParser->getTypeName to convert to human readable form. HTMLPurifier_VarParser still accepts strings.
- Parser in config schema only used for legacy interface
