Adding Greek support in Full-Text search

From a SAC case:

We'd like to have Greek Lucene indexing support added into JIRA. We've done a core modification for one of our customers, but we would really like to see it in the official codeline.

Objects affected:

• jira/src/etc/languages/default/com/atlassian/jira/web/action/JiraWebActionSupport.properties

  admin.jira.allowed.language.greek=Greek
  

• /jira/src/java/com/atlassian/jira/config/properties/APKeys.java

      public class Languages
      {
          public static final String ENGLISH = "english";
          public static final String GERMAN = "german";
          public static final String GREEK = "greek";
          public static final String RUSSIAN = "russian";
          public static final String CJK = "cjk";
          public static final String OTHER = "other";
      }
