[jdk7u-dev] Request for approval: 8020663

Hi folks, a clean backport:

8020663: Restructure some properties to facilitate better translation
http://hg.openjdk.java.net/jdk8/tl/langtools/rev/a76dc1b4c299

As per the description:
javadoc has some properties which define the javadoc comments for 
mandated methods. These have a specific structure, in which white space 
is significant. It would be better if these comments were broken apart 
into the structural elements (@param, @return, etc) and the text which 
would need to be localized.
