версия с поддержкой udp (частичной. не верно оправляется и принимается пока)
Merge pull request #1 from slevinkelevra/master

want to merge
after merge.
add class for XML, check UDP protocol
sending message from server broadcast to clients (and to sended client too, becouse there is no identification of client except init cmd)

udp on xml
tcp - not. need do it
after uvd24.

some fix bugs
not multiple connect  to server in TCP mode
chat done for UDP

use id from client in his message and don`t send to it message again
tcp can parse XML format
small refactoring + spetial host if not "@" + port comes to servers
command line parser has been added
