        - fixed build rules to match other projects

        * WebCore.pbproj/project.pbxproj: Set deployment target to 10.3 in the build styles.
        When built without a build style (by Apple B&I) we want to get the target from the
        environment. But when built with a build style (by Safari engineers and others), we want
        to use 10.3.

        * Makefile.am: Took out extra parameters that make command-line building different from
        Xcode building. Now that this is fixed, you should not get a full rebuild if you switch
        from command line to Xcode or back.
