ElasticTypeName will replace dots with underscore, the contextHolder now search for the mapping on the raw ElasticTypeName and not a string build from the index & the type.
Should fix issues #59 and issue #60. Will need re-indexation though !

Also added a fixed value for the release plugin (3.0 only work with grails 2.3)
And added a default value for the configuration (in the test app)
