Package creation always enabled for context menu.
Package exporting will ask user to overwrite if a package already exists at the chosen path.
Package creation will create a new package directly instead of showing a naming dialogue.
New package is selected in file view and renaming is active.
Naming dialogue is gone.
Tests adjusted.
AppDelegat reuses context menu command.
Some warnings fixed.
dispatch_get_current_queue deprecated replaced with dispatch_get_main_queue.
Removed some debugging logging for autoplay setting.
