term: add term_set_user_mouse_cursor()

Browse source 
This function allows setting a custom mouse cursor.

This is done by adding a ‘char*’ member to the term struct. When it is
non-NULL, we *always* use that pointer (the exception being when the
pointer is hidden), while the pointer is over the grid. This is
instead of the hand/beam pointers we otherwise would use.
