Allow themes to be disabled in rline

Browse Source 
This still outputs ANSI color escapes, they're just always for color 9,
which is the default color for the foreground or background. rline will
always output escapes, as it's fundamentally part of how it works. If
you don't want ANSI escapes, disable rline.
