I went through and cleaned up all the warnings that I could, which involved fixing some of the plugins. The configure.in script was re-arranged and cleaned up so, and a check for libtool 1.3.5 was added to autogen.sh. Added checks for Gtk and GNOME. Some plugins were removed from the list of things to build for various reasons. Added GST_DEBUG_FORCE_DISABLE in gstgetbits, since that's time critical and even an if() from a DEBUG can significantly increase runtimes.
