[Dillo-dev] patch: dw configure args: rtfl and doublebuffer

I saw in the bug tracker that --disable-rtfl still turns on rtfl msgs. Did some reading. The third argument to AC_ARG_ENABLE is always run if the option was specified, regardless of the value. If the option is not specified, the fourth argument is run. --disable-FEATURE just becomes --enable-FEATURE=no. (I'll send a separate patch to Jorge to allow compilation with rtfl.)
