This fixes issues with search not updating when something on the data model is changes e.g. via drag and drop. Also this fixes a display error that occured when an entry was dragged into the selected group in the outline view which would then show the group contents and not the search results
* Set password creator window title
* Fix TODO, help url is read from Info.plist instead of a string literal
* Remove width constraint for 'Set Defaults' button of password generator so text is not cropped
* Improve keyboard shortcuts
New entries can be created using cmd + n, while cmd + shift + n creates new groups. Creating new databases is probably done too rarely to warrant a keyboard shortcut.
Additionally the 'New' menu item now has a submenu containing actions to create new entries, groups and databases (fixing #405).
* Hook up keyboard shortcut cmd + backspace to delete action
* Use shorter date format in inspector and add special output for distant future
* Show date picker when expiration is activates for either groups or entries but no date set
* Prompt for key file pops up automatically when the field is selected using tab
* Focus title field when new groups are created (#606).
* Rename search method so text fields don't capture it (#531)
* Don't show empty tags
* Remove menu item used for debugging.
