[theme] Almost minimal transparent `tty_theme`

Good day,

You will find below a theme I wrote because I happen to use a variety of terminals which sometimes makes fully colored themes hard to use. It is a slight evolution of fully colorless theme where elements where only highlighted with bold fonts and reverse video.

The very few touches of green and red make me feel it is quite elegant. Feel free to adapt with your favourite colors. :-)

The usage of bold and colors simultaneously makes it best suited for dark backgrounds with clear fonts. By suppressing the combo bold + colored, you should obtain something adapted on clear backgrounds too.

Enough words, now the theme:
background = default default
frame = default default
window_title = default default
directory = default default
selected_directory = default default reverse
playlist = default default
selected_playlist = default default reverse
file = default default
selected_file = default default reverse
marked_file = green default bold
marked_selected_file = green default reverse,bold
info = default default
selected_info = default default bold,reverse
marked_info = green default bold
marked_selected_info = green default bold,reverse
status = default default
title = default default bold
state = default default
current_time = default default bold
time_left = default default bold
total_time = default default bold
time_total_frames = default default
sound_parameters = default default bold
legend = default default
disabled = red default
enabled = green default bold
empty_mixer_bar = default default
filled_mixer_bar = default default reverse
empty_time_bar = default default
filled_time_bar = default default reverse
entry = default default
entry_title = default default
error = red default
message = green default
plist_time = default default

Best Regards.
