Modified content:

-Motd
-TeamMenu
-Classmenu
-BuyMenu
-UI Sounds

Tips:
-To disable the Motd menu (which I consider irrelevant). delete or rename the cstrike/motd.txt file, so that menu will be skipped when loading the game.

-If you want to go back to your default theme, make a backup copy of the folders (classes,resource,sound/ui) and copy again and replace it

*Any suggestion of changes is welcome.
