Observer cannot use chat functionality

[xezon]

Observer cannot use chat functionality.

GenTool fixes this by hacking following addresses (game.dat):

0x5AE45C > NOP 8 bytes to enable Observer HUD
0x5ED4B5 > NOP 12 bytes to enable Observer Backspace Button
0x5ED509 > NOP 12 bytes to enable Observer Enter Button
0x5ADE51 > NOP 8 bytes to enable Observer Chat after Surrender
0x5EE7A6 > NOP 8 bytes to enable Observer Diplomacy Screen after Surrender

(NOP meaning No Operation aka 0x90 for x86)
