* 24-bit direct color support (patch by Fengguang Wu)sf-exg2016-06-211-0/+133

It'll not only modernize their look and feeling, but also bring more eye friendly color schemes. Very helpful for long time programmers. To avoid memory overheads and keep the patch non-intrusive, it takes the approach to adapt the nearest color in an hidden 6x6x4 (88-color mode) or 7x7x5 (256-color mode) color cube to the new 24-bit RGB color. The pros/cons are: +) least memory footprint (close to 0) comparing to konsole, gnome-terminal etc. real 24-bit arrays +) exact colors and excellent user feelings comparing to xterm, mlterm, etc. approximating to 256 palette +) usable in both the existing 88/256-color modes Most vim GUI color schemes show up the same as gvim in rxvt-unicode's 88-color mode, not to mention the 256-color mode. Typical applications only use one or two dozens of colors at the same time. -) may not be able to show 2+ close 24-bit colors RGB colors close to each other will likely fall into the same slot in the 6x6x4 or 7x7x5 color cube. If necessary, it could be improved effectively by implementing some collision avoidance logic, trying to find empty/eldest slot in the +1/-1 r/g/b indices (ie. 3-8 neighbors). The CPU overheads of map_rgb24_color() look ignorable: I feel no perceptible slow down when doing vim operations in 24-bit color mode.
