<Swing Dev> [8] Review request for 4199622 RFE: JComboBox shouldn't sending ActionEvents for keyboard navigation

[Vladislav Karnaukhov]

Hello,

please review a new version of the fix: 
http://cr.openjdk.java.net/~vkarnauk/4199622/webrev.02/

Support for VK_PAGE_DOWN/VK_PAGE_UP and VK_HOME/VK_END keys was added; 
test routine was altered accordingly.

Regards,
- Vlad
