Feature Request: Allow for color customization

Is your feature request related to a problem? Please describe.
It is extremely difficult to read Taskbook's output with my terminal colors

Describe the solution you'd like
Because terminal styling is highly irregular, allowing users to configure the color hexes in the ~/.taskbook.json would be the ideal solution.

Additional context

This is on iTerm 2 Build 3.2.20180723-nightly in ZSH, with theme "af-magic"

That would be useful, because it's unusable with zsh and agnoster theme.

This feature request for color customization includes your request for customizing grey text, as well as the ability to customize all colors. So, it seems like the best solution would be to ignore your previous request in favor of implementing this one.

I would definitely love to see this feature implemented! Considering the irregularity of terminal styling, as you also mentioned, the ability to customize the colors would not only a great bonus feature for configuration, but also a potentially necessary feature for some users. Here's to hoping this request is considered!!!
