If you have GTK installed on your system but want to build without it anyway (e.g. if you're buliding a package suitable for headless systems), it's useful to be able to explicitly instruct PuTTY's build system not to use GTK even if it's there. This would already work if you unilaterally set PUTTY_GTK_VERSION to some value other than 1, 2, 3 or ANY. Added NONE as an officially supported option, and included it in the list that cmake-gui will present. Also, made the check for libX11 conditional on having GTK, since there's no need to bother with it otherwise.
