Update ko.expressionRewriting.preProcessBindings:
Add support for function-wrapped binding values (based on option).
Add support for dynamically created binding handlers (like my key.subkey plugin) using ko.getBindingsHandlers.
Add support for preprocessing bindings using <handler>.preprocess.
Add specs for binding preprocessing.
Add comments for the regular expressions used in parseObjectLiteral. Add comments about current parsing issues (and a failing test for one). Alter one of the expression rewriting tests so that it fails if the codes doesn't have the regular-expression-literal match.
Updated parseObjectLiteral to parse a slash as either division or regex.
Remove unneeded parentheses in the regex.
Clarify that "two way bindings" is an internal implementation detail, not a public API
