Added Lighthaus Theme

[Brutuski]

Lighthaus theme for vim-airline v 1.0.1

A focused dark theme with a mix of vibrant and subdued colors that helps you see changes as and when they occur in your vim-airline. Makes it very easy to visually identify and differentiate vim modes and changes. The colors used for the 4 modes have a min contrast ratio of 4.5 against the background WCAG2.1 For more information head over to the Lighthaus Project Repo and the Lighthaus Vim Repo.

Changelog is maintained here.

Done.

okay thanks.

Added some description and links for further information.

What I meant is please add at least the theme name to here:

https://github.com/vim-airline/vim-airline-themes/blob/master/doc/airline-themes.txt

You don't seem to have configuration variables, but at least mention the theme in the help file for this project. Thanks.
