changed references of cdmlib-remote-webapp to cdm-webapp
minor
implementing option to update the database scheme via cdmlib-remote, but blocked by #3910 (eu.etaxonomy.cdm.database.ICdmDataSource is not compatible to javax.sql.DataSource)
datasources.xml file is now configurable, the eclipse launcher expects now ~/.cdmLibrary/datasources-cdm-server.xml
start, stop of instances and reload of configuration implemented, see #3471 (cdmlib-remote-webapp instances can be stopped / started individually)
refactoring in preparation for #3471 (cdmlib-remote-webapp instances can be stopped / started individually)
