Review request for MACOSX_PORT-675: VK_DELETE does produce an extraneous character in a TextArea or TextField

[Leonid Romanov]

Hi, 
Please review a fix for http://java.net/jira/browse/MACOSX_PORT-675

A bit of background. NsCharToJavaChar is a function contributed by Apple that translates a small subset of NS characters into Java characters. This function is currently unused. This fix does two things:
- Puts NsCharToJavaChar back to use
- Modifies a table used by NsCharToJavaChar to ensure that NSDeleteFunctionKey and NSDeleteCharacter gets translated regardless of what current modifiers are.
