[TASK] Enforce shortcut title to be set by controllers

The ShortcutRepository should not deal with generating
shortcut titles based on the provided arguments. This can
never be reliable, especially for custom extension code.
The appropriate title must be set by the calling controller
since this is the place where all necessary information,
to define such title, are available.

Therefore, adding a new shortcut button without defining
a display name is deprecated. All Core controllers are
adjusted to provide the necessary title themself.
