Changes: The new mode DECIMAL_ENG adds engineer notation: numbers are displayed as 100e-6 instead of 1e-4. It can be switched on and off with the commands "eng" and "dec". This release adds also some command shortcuts: "deg", "rad", "pol", and "rect". The comma is now interpreted as a point to cope with some international keyboards.
