changed: when winix demonizes it creates a three new descriptors (0, 1 and 3)

pointing to /dev/null
added:   DbBase::AssertValueBin(PGresult * r, int row, int col, std::string & result)
         it reads binary (bytea) data
added:   DbTextStream can handle 'bool' types now
         (is puts 'true' of 'false' to the stream)
changed: now passwords can be stored either as plain text, a hash or can be encrypted
         with RSA
         currently we have following hashes:
         md4, md5, sha1, sha224, sha256, sha384, sha512
         we are using openssl to manage them
         (look at config options for more info)
changed: winix version to 0.4.7         
added:   class Run - you can run any program from os and send a buffer to its standard input
         and read what the program put on its standard output
added:   class Crypt (in System) - calculating hashes, and crypting/decrypting
