Adding version checks in xprotect_re-enable_java_6_and_7.sh for com.apple.java.JavaAppletPlugin and  com.apple.java.JavaPlugin2_NPAPI

Apple added two new version checks to
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtec
t.meta.plist. The first new check looks for Apple's
com.apple.java.JavaAppletPlugin Java browser plug-in identifier. This
Apple Java browser plug-in is running on Mac OS X 10.6.x or was
installed on 10.7.x or later by Java for OS X 2012-005 or earlier.
Installing Java for OS X 2012-006 and later automatically removes the
Apple Java browser plug-in.

The second new check looks for Apple's com.apple.java.JavaPlugin2_NPAPI
Java browser plug-in identifier. In this case, the Apple Java plug-in
was re-enabled using the procedure in the following Apple KBase
article: http://support.apple.com/kb/HT5559

This update also removes the Oracle Java browser plug-in version check
from 10.6.x's XProtect. Both new Apple Java version checks and the
Oracle Java browser plug-in version check are in the 10.7.x and 10.8.x
XProtect.
