Messed up pip installation

[scaphilo]

The pip installation now creates a library called site_packages/apps/accounting and so on
but it should actually create a site_packages/koalixcrm/apps/accounting and so on
Also the imports in all files need to be adjusted back to koalixcrm.apps.accounting instead of apps.accounting
this has to be fixed for all packages crm, accounting, subscriptions and djangoUserExtension

Also the pip installation creates packages called koalixcrm.settings because the automatic search_packages is looking for folders with init.py
