SF 0.55 Test

Update：
1，An edit box is added to setup Max Latency Limit for server, bigger than this value will be rejected.
2，fix the bug that when chatting in the channel and game lobby, a empty line will be added every sentence.
3，fix the bug that loading progress bar is not work
4，it can display News and Homepage in game now
5，when exit the game, sometimes there will be a voice and a message box of warning, it did not affect playing, so you can ignore it.
6，there is some white space in username and channel name, we cannot remove it all in a short time, so we just reduce the some width of white space.
7，the username in game is limited to 18 english char or 6 chinese char or UTF-8 string of 18 bytes, if more, it will be truncated.
8，for symmetric, the host in game will be added '★' both sides of the username.
9，in some low speed network, the function of WAN IP may cause the extra launch time of SF, it is fixed now and program will not wait the result of WAN IP.
10，1 Player vs 1 AI is added in multi-mode, you can use add-ai buttom in game lobby and then can choose race and hard level.(it is different from 0.44 version, not by the menu on right). and the vs AI in single-mode and multi-mode is not same. single-mode do not need network so it is no lag, but multi-mode need and have some lag, but if lag is very heavy, tell me.

Known issues:
1，in some cases, after you launch the SC2 game, you find the game is laggy and CPU is high, try to restart the game to see whether it is good.
2，hot key can not stored for next time using.
3，no count second before game start
4，can not change colour
5，the launch time of the SF program is too long.
