updated installer to bootstrap v4
Merge branch 'master' of https://github.com/kajona/kajonacms
Installer updated to Bootstrap 3
NEW: module_installer | installer -> started to merge the installer changes by ChrDr
NEW: module_installer -> continued the migration to boostrap 3
NEW: module_installer -> added a helper to get the installation state
NEW: module_system | endprocessing event -> all entry-points (index, xml, image, download, installer) are now triggering the afterendprocessing event
NEW: module_system | events -> added a new event "core.system.request.aftercontentsend": Invoked right after sending the response back to the browser, but before starting to shut down the request. This means you are not able to change the response anymore, also the session is already closed to keep other threads from waiting. Use this event to perform internal cleanups if required.
NEW: module_installer -> the mode-selector is only shown in case there's no system installed yet
NEW: module_installer -> style cleanup
