resources for lzbench

[tansy]

Hello, I committed few icons for windows. Whoever wants to use then is welcome.
I put it in tgz pack. There is an instruction, Makefile patch, and mentioned icons. There are also some slightly different icons to choose from in zip file in _lzbench/res/.
You can use them freely. Only don't change to rainbovv colours or things like that.

To compile resources placed in _lzbench/res/ run make with parameter:

$ make BUILD_RES=1

PS. "Doubled" rule for .rc.o is intended as single doesn't want to work (as explained here)

.rc.o:
	windres $^ -o $@
%.o: %.rc
	windres $^ -o $@
