Allow setting a custom host color
This change allows someone to change their host color by adding the
following to their `.bash_profile`:
# change to red
THEME_PROMPT_HOST_COLOR="red"
# change to green
THEME_PROMPT_HOST_COLOR="green"
Any variable inside the `colors.theme.bash` can be used and it will be
evaluated at the last minute.
