        Cleaned up my last patch after further considerations

        * loader/icon/IconDatabase.cpp:
        (WebCore::IconDatabase::pruneUnretainedIconsOnStartup): Uses the new checkForDanglingPageURLs to check
          for and fix danglers.  Does so in all builds (changed from debug only in my last patch)
        (WebCore::IconDatabase::syncDatabase): Uses the new checkForDanglingPageURLs to check for danglers
        (WebCore::IconDatabase::checkForDanglingPageURLs): This checks and, if asked via an arg, prunes the dangling pageURLs
        * loader/icon/IconDatabase.h:
