* DRY, standardized window top offset
* handle_splash_events() handle multiple events per frame
* accurate windows menubar height for multiple rows
* Windows filter a resize event triggered by the menubar
* windows expand small window to fit menubar
* splash screens draw in view rect, not window rect
This commit only updates the XCode project for the changes.
A later commit each will update it for scons and MSVC.
A few actual changes are mixed in:
- Add a prefix header for a handful of common definitions
- Moved current_cursor into the Cursor class as a static member
- Removed the make_cursor_sword and make_cursor_watch functions
- Include tests in the All target
- Remove redundant -l flags for Common and Common-Party (since they're included in the Link phases anyway)
