Improvements to the usability of the number entry widgets (Priority, Level Emitter, Craft Amount): (#4737)

- Fixed tab order
- Introduced focus state for corner buttons
- Allowed the player to enter any text, but add validation that only persist it if it is a valid number
- Enter will now confirm these dialogs and return to the previous dialog
- The text field is automatically focused and its contents are selected
