Calc4M: less bugs, more touchscreen options

Mobile java calculator Calc4M does basic and scientific calculations, has lots of conversion options, all the important physical constants are built in, and the user interface is really good.

The latest version features some slight cosmetic fixes, a bug with the # key on newer Nokia phones has been ironed out, and touchscreen users can do more tricks, such as clearing the screen with a single sweep.
