Better Theming Options.

[chetanmadaan]

With the new Theming options in Astroid 2.2.0, room for 2 new features/enhancements is available.

1. Ability to use the theming colors wherever color picker is used, background color, text, shadows and what no.
2. Create theme colors (auto create), based on a single brand color.

Jonathan Shroyer contributed the code for the 2nd item above and the idea as well. If we ever release number 2 as a feature for Astroid, the credit goes to Jonanthan. Jon's github is at: https://github.com/learncss and website at: http://www.designinnovations.net/
