Free42: Unlimited-length strings and other type extensions

[SammysHP]

What about doing it the other way around? Add all the bells and whistles to Free42 and create a fork like "Free42 Classic" that only contains features of the real HP 42s. So even features like time and location should be removed from the classic version. If someone wants these features he can use the "normal" version of Free42. As long as all changes are backwards compatible there are only very few reasons to not use that version and if someone prefers a clean version he can use "Free42 Classic".
