update tcell to v2 and enable TrueColor support

Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.

Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.
