Code review request for more informative comments in SourceVersion

[Joe Darcy]

Hello,

It was recently been brought to my attention that the SourceVersion enum 
in javax.lang.model did not have informative descriptions of the 
language changes in Java SE 7 and 8.

Please review the patch below which add this information.

Thanks,

-Joe
