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

<p style="margin-top: 0; margin-bottom: 0">&nbsp;</p>
<p style="margin-top: 0; margin-bottom: 0">ReactOS Calc allows the calculation of three types of trigonometric functions with their inverse operations.</p>
<p style="margin-top: 0; margin-bottom: 0">These functions can be used with three different angular
units of measurement: degrees, radians or gradians.</p>
<p style="margin-top: 0; margin-bottom: 0">The angular mode does not affect the non trigonometric functions.</p>
<p style="margin-top: 0; margin-bottom: 0">Please note that the degree type uses decimal degrees and not angles in the degree-minute-second form.</p>
<p style="margin-top: 0; margin-bottom: 0">The available functions are:</p>
