Bug 696498 - Remove NPOTB makefiles from toolkit-makefiles.sh & cleanup variables; r=khuey

* Remove MAKEFILES_plugin since not assigned anything
* Rename MAKEFILES_libpr0n to MAKEFILES_imagelib, to match bug 66984
* Remove the following NPOTB makefiles:
    parser/htmlparser/tests/logparse/Makefile
    intl/unicharutil/tools/Makefile
    xpcom/reflect/xptcall/src/md/test/Makefile
    xpfe/components/autocomplete/Makefile
    xpfe/components/autocomplete/public/Makefile
    xpfe/components/autocomplete/src/Makefile
* Remove the following commented out makefiles:
    parser/htmlparser/tests/outsinks/Makefile
    xpcom/reflect/xptcall/tests/Makefile
    xpcom/reflect/xptinfo/tests/Makefile
* Remove embedding/tests/winEmbed/Makefile since it belongs in xulrunner/makefiles.sh

toolkit/toolkit-makefiles.sh
