[dev] [dvtm] Truecolor support

[Paride Legovini]

Hi,

I see that st nicely support "truecolor" sequences, as it can be easily 
tested with this command:

printf "\x1b[38;2;255;100;0mTRUECOLOR\x1b[0m\n"

that has to be given outside any terminal multiplexer. The point is that 
currently no terminal multiplexer (tmux, dvtm, screen) supports this 
kind of color sequences. I'd be interested to see this feature added to 
dvtm, but I'm not sure if it is possible as it may be a limitation of 
libncurses.

Did anybody try to implement this before?
