Improved cross-project references in Xcode 3.1.1

This is your new friend when you have sub-projects in Xcode that build frameworks that the parent project needs to link to and find headers for:

FRAMEWORK_SEARCH_PATHS = "$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)"

This is much better than the old framework search path of [name of other project]/build/${CONFIGURATION}/ (since that depended on the subproject building into ‘build’ folder (which isn’t happening when you e g have a system-wide build folder)
