JDK 7 BOOT JDK updated to JDK6u14 FCS

[Xiomara Jayasena]

The JDK 7 BOOT JDK has been upgraded from JDK 6 to JDK 6u14 FCS for the 
official RE builds.

The next build (b62) will be built and promoted with the new BOOT JDK. 

The README-builds.html has been upgraded with this information in the 
build integration area:
http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html 
and the README-builds.html and the changes will be reflected in the 
master repos the next time the build integration is synced.
