This patch implements some 256 colour support for Irssi up from the previous 16 colours. Initial parsing of the %x/%X format codes is implemented and the parser accounts in advances the char* for that. The colour attributes are widened from 4 to 8 bit. The colour protocol is changed to a new format. Some pointers to remaining work are written in the comment in textbuffer.h. Note that Irssi already does support requesting 256 colours from the terminal in the original source code, so this part did not have to be touched.
