New version of calc written by Carlo Bramini (carlo(dot)bramix AT libero.it) Better than the one we currently have. For now in rosapps, so we can test it, if it's all working fine, we should replace the wine one. Changes by me: use pow() instead of cbrt(), as cbrt doesn't work in our tree. I imported the whole codebase, although the mpfr files are not used. I moved the localizations to "lang" and the icons to "res" subfolder. svn path=/trunk/; revision=31512
