Terminal: add bg color handling + PDBG

Browse Source 
Set the right bg color instead of using a dimmed version of the fg
color. The colors are stored in the first 6 bits of the color index.
Thereby the first 3 bits contain the fg and the second 3 bits the
bg color.

The debug message in _handle_esc_seq5() now shows the sequence in
question.

Fixes #495.
