[icu-design] UCharacter.MIDNUMLEFT -> MIDNUMLET

[<yos...@us...>]

After ICU4J 4.0 d02 was published, we identified there was a TYPO in a new 
Wordbreak type constant in com.ibm.icu.lang.UCharacter - 
http://bugs.icu-project.org/trac/ticket/6355

        /**
         * @stable ICU 4.0
         */
        public static final int MIDNUMLEFT = 11;

This constant was newly introduced in 4.0.  Although APIs are basically 
frozen for 4.0 release by our policy, we do not want to leave the mistake 
and we believe there is no impact to ICU customers.  So we will correct 
the name in 4.0 d03 release - 


        /**
         * @stable ICU 4.0
         */
        public static final int MIDNUMLET = 11;
