Improve system property based configuration of file repositories.
 - Created new SystemFileRepository manager which generates configuration objects for the regular filerepository component
 - Removed specific system property versions of filerepository components
 - Replaced generic file repository component with purpose specific (navajo,multitenant,tipi) components.
Remove obsolete and probably broken run configuration
Update target platform
Refactor names of queuemanager to be more consistent
Fix default (instance less) datasources with aliases
Re-implement some of the handling of tenant specific scripts.
Trying to get the names right: rpcName = without (optional) tenant suffix.
scriptName / scriptPath: with (optional) tenant suffix

There might be a problem with scripts that have a '_' in their path.
