HiContrast icon theme. Some more code removal, but I gave up soon to focus on up-streaming the icon switching patches.
Up-streaming the icon switching patches. Created the iconswitching1 CWS and committed all the available patches there, removed --with-icons configure option and made the themes building by default, rewrote hicontrast-to-theme.sh to Perl to work on Windows as well, and built the CWS.
Minor. Tried to help with debugging of an Impress crasher a bit.
