Currently every loaded module starts with hardcoded default colors,
ignoring current value of variables normal_color and highlight_color.
This provides inconsistent experience because which color is actually
used for terminal window depends in which place of grub.cfg color is
set. Additionally even if color is set in terminal window, terminal is
closed and reopened again, color is reset to hardcoded default.
The patch makes sure current values are applied on module load. Also
normal_color is applied when new instance of terminal window is created.
In principle this patch makes term->normal_color and
term->highlight_color redundant, as there is no place where they are set
individually, they always follow variables normal_color,
highlight_color.
