Mouse cursors now work again

- centralized screen-level cursor changes, no more operator
  running for it.
- spacetypes have callback to check/set individual cursor
  types. Use notifier SCREEN_CHANGED to make sure it works
  on mode changes etc.
- new calls WM_cursor_modal() and WM_cursor_restore() to
  make temporarily cursor types during modes.
- used above for view2d cursors.
