JDK8 RFR JDK-8029237 Update copyright year to match last edit in jdk8 jaxws repository for 2013

[Miroslav Kos]

Hi,
this is about fixing copyright years for jdk8 (!); the incorrect years 
found for both 2012 and 2013, so not to confuse script
jdk8/make/scripts/update_copyright_year.sh
it is necessary to use option -d "<date>" for commit. I tested that and 
it seems to work perfect.
I used following:

[2012 modifications]
hg commit -u mkos -l ../2012-msg.txt -d "2012-12-30"

[2013 modifications]
hg commit -u mkos -l ../2013-msg.txt -d "2013-12-30"

When commits performed with past date, update_copyright_year.sh script 
finds those in proper years. Since I am not familiar with using webrev 
for pushing changes, I exported both revisions into separate patches:

2012: http://cr.openjdk.java.net/~mkos/8029237/copyrights-2012.patch
2013: http://cr.openjdk.java.net/~mkos/8029237/copyrights-2013.patch
all changes webrev: 
http://cr.openjdk.java.net/~mkos/8029237/webrev-all.00/   (upload still 
in progress, I hope it doesn't take more than 30 mins)
bug: https://bugs.openjdk.java.net/browse/JDK-8029237
