[8] Review request for 8019265: [macosx] apple.laf.useScreenMenuBar regression comparing with jdk6

[Leonid Romanov]

Hello,
Please review a fix for 8019265: [macosx] apple.laf.useScreenMenuBar regression 
comparing with jdk6 . The problem here is that NsCharToJavaChar() function we 
use for translating keystrokes returns CHAR_UNDEFINED for keys like arrows, 
which is undesirable in case of CMenuItem.
