* Add rebindable syntax for if-then-else
There are two main changes
* New LANGUAGE option RebindableSyntax, which implies NoImplicitPrelude
* if-the-else becomes rebindable, with function name "ifThenElse"
(but case expressions are unaffected)
Thanks to Sam Anklesaria for doing most of the work here
