This allows widgets to be positioned relative to other widgets.
Two dialogs have been converted to use relative positioning.
Also fix some issues with calculating the dialog rect.
- Refactor dialog format parameter management to use a single protected control function
- Format parameters "frame" and "frame style" merged
- Colour is now a first-class format parameter (though it still has a separate setter)
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)
