- KIWIAnalyse: store exported dbs in <template>/root/var/cache/dbs
  so they will be imported automatically
- KIWIAnalyse: use `mysqladmin ping` instead of a
  netstat+grep to check for running mysql database
- KIWIAnalyse: added function importDatabases() to KIWIConfig.sh
  in order to allow the import of complete database sets. This is
  the counterpart for the recently added KIWIAnalyseCustomData
  function createDatabaseDump()
- the config.sh created by KIWIAnalyse will automatically add an
  entry to call this function to allow the reimport of the databases
  during image creation
