1.12.1

• project group configuration changed from list to map. In the configuration that would be from:

  <void property="groups">
   <void method="add">
    <object class="org.opengrok.indexer.configuration.Group">
     <void property="name">
      <string>foo</string>
     </void>
     <void property="pattern">
      <string>foo-.*</string>
     </void>
    </object>
   </void>
  </void>

to the following (note the change of structure and also in the method):

  <void property="groups">
   <void method="put">
    <string>foo</string>
    <object class="org.opengrok.indexer.configuration.Group">
     <void property="name">
      <string>foo</string>
     </void>
     <void property="pattern">
      <string>foo-.*</string>
     </void>
    </object>
   </void>
  </void>
