Add bright foreground color option

It was requested in jwilm/alacritty#825 that it should be possible to
add an optional bright foreground color.

This is now added to the primary colors structure and allows the user to
set a foreground color for bold normal text. This has no effect unless
the draw_bold_text_with_bright_colors option is also enabled.

If the color is not specified, the bright foreground color will fall
back to the normal foreground color.

This fixes #825.
