Adjustments multiplayer name (Hints/ Captions) + training hint

[T-MaxWiese-T]

• Removed a wrong hint [SwatServerBrowserMenu_NameLabel]
• The text now has a green color (GameSpy style). Bring more color into the game and this makes the name field more conspicuous. Also, the text is now better than before the same with Host Game
• Player name has been renamed to MP name everywhere because strictly speaking it only affects the multiplayer, nothing else
• Name changed from eezstreet to Operator (avoid misuse)
• Hint for training has been extended
• [SwatServerBrowserMenu_NameLabel] wrong hint (Start Mission) removed
