- replaced list(...) = unpack('...') calls with extract(unpack('...')) (thanks martinu!)
- added pure-php implementations of md2, sha256, and sha512 to Crypt_Hash - added setPrecision() to Math_BigInteger - other small fixes git-svn-id: http://phpseclib.svn.sourceforge.net/svnroot/phpseclib/trunk@56 21d32557-59b3-4da0-833f-c5933fad653e
