Some more tweaks to cursor handling

- Fix cursor turning into a sword during universe shifts
- Hide cursor along with menubar during splash screen
- Add watch cursor, used during splash screen
- Properly restore cursor after a dialog
- Use sword cursor for dialogs
- Show ibeam cursor in dialog text fields
- Move everything cursor-related out of graphtool
