Calculator App Lua (WIP1.5) v2.0

Stuck again at the character limit until 1.5...

I have the basic graphics done and the number translator running with decimals, had to shorten it to 7 digits for the floating value problem... pi and clear are the only things running at the moment. Ill try to shorten some of the code and hopefully I can squeeze in the operator calculations, sigh.

1.1: just when I thought I had some room... "oh right, NEGATIVES", *facepalm*. Anyway can now input negatives, and square root and square will at least return a number now.

2.0: Calculator is functioning! But no room to finish the displays and series calculations, you'll have to clear after each use.
