Patch issue

Fix issues #8 and #9.

add Java 9 macOS integration

Added support for macOS UI integration using new java.awt.Desktop APIs introduced with Java 9.

It is worth noting that jGAF remains fully compatible with Java 8; jgaf-2.4.0.jar is compiled using JDK 8.

In other words, you can now use jGAF with JRE 8, 9, 11, etc.

Update EZUIStarterListener API

Changes:

• update EZUIStarterListener API: add frameDisplayed() method
• dropped down support of JDK 7; now JDK 8+ is required
