Summary: Reorganized scientific funtions for RPN.

RO Scientific offer the following scientific functions in one panel: pi, log (log base 10), 10^x, ln (natural log), e^x, sin, cos, tan, asin, acos, atan, rad<->deg conversion, decimal hours<->h:m: conversion.

h:m:s is displayed as ...h.mmssff...
- ...h is one or more digits of hours
- mm is 2 digits of minutes
- ssfff is two digits of seconds followed by fractional seconds
