Reworked generic definitions in both CursorMenus and Applications to remove the necessity of creating a new cursor menu for each new cursor element type.

• Breaking change: expect dependents to break upon release of this version. They should only need to specify the highest type of cursor element they wish to use for their applications (e.g if they do not use counters, they should use CursorElement in the application specification)

Implemented CounterPageApplication which allows both pagination and counter interaction (the respective controls from both are on separate key binds).

Added default return to CursorOutputElement.ApplyFunction() if no Func was provided.

Changed display of the output string in BoxedOutputScreen to allow unity string tags without affecting the box of the screen used, such as coloring of the text.
