KSirc native

Format:

˜<fg>[,<bg>] sets the foreground and background
˜c resets to defaults
˜b sets bold font
˜u sets underline
˜i sets italics
˜r sets reverse video

Why did I change KSirc to use ˜ instead of 0x03 (Ctrl+C)? Well, it's hard to use 0x03 in scripts and not all C functions seem to like it. ˜letter also allows more commands while not stomping on mIrc's future changes.
