[8u60] RFR: RT37399: Mac: Command-period generates spurious KeyEvents on Mac OS

[Morris Meyer]

Kevin and David,

Could you look over my fix for this issue?  I thought about putting the 
special casing in the GlassViewDelegate and changing the return value of 
sendJavaKeyEvent to return a boolean.  I think this way might be a bit 
cleaner.

This issue is caused by the MacOS processing of Command-DOT, which when 
triggers causes two performKeyEquivalent: NSEvent *event invocations 
which were giving us spurious KeyEvents.  The fix special cases the 
Command-DOT and returns YES which nicely eats the second 
performKeyEquivalent.

Thanks,
