Updates ICU4J from 4.4.2 to 50.1.1

GWT uses ICU4J for formatting dates and times in translated messages.
See com.google.gwt.i18n.rebind.DateTimePatternGenerator.

For example, the token "{0,localdatetime:tz=$tz,yMd hms}" was previously rendered as
"2/1/2010 7:04:05 PM" in English and is now rendered as "2/1/2010, 7:04:05 PM"
(with an extra comma). Other major changes to ICU4J since 4.4.2 are available from
this web page: http://site.icu-project.org/download
