JavaFX 2.2.2 version number change to 2.2.4

[Kevin Rushforth]

In order to align with the recent change in JDK version number as 
explained here:

http://www.oracle.com/technetwork/java/java-update-release-numbers-change-1836624.html

the JavaFX version number for the 7u10 release is changing from 2.2.2 to 
2.2.4. The 7u10-b07 build, which will be pushed to java.net later this 
week, will include 2.2.4-b07. Note that weekly JDK 7u10 builds can be 
downloaded from java.net at:

http://jdk7.java.net/download.html

We are also in the process of renaming the openjfx/2.2.2 repositories on 
openjdk to openjfx/2.2.4. I will send another update when that happens.
