* There is now a server_read_only_memory structure that is placed in a (surprise!)

read-only area shared between the Desktop and all applications.
* Right now, this area only contains the desktop colors, ie. B_PANEL_BACKGROUND_COLOR
  etc.; ui_color() no longer needs to ask the server for these colors.
* The ui_colors are now maintained by DesktopSettings, though ColorSet is still there.
* The default colors are now hardcoded once and for everyone in InterfaceDefs.h, ie.
  the app_server uses them as well.
* Desktop::Init() can now also return an error (but that is not yet accounted for).
* Cleaned up InterfaceDefs.h.
* Fixed wrong include in moreUTF8.h.
