tshark: add "--color" option emulating wireshark colors
With this commit, tshark will mimic the packet coloring present in the
Wireshark GUI whenever "--color" is passed. This initial commit only
adds such support for the standard text output format. A future commit
could potentially broaden this support to other output modes (such as
"-V" mode).
