Nested Bullet Outlines

Thanks to Keith Miyake (@kaymmm) we now have support for nested bullet outlines.

What this means is that when you indent a bullet using either <c-t> or >> the next bullet would be of a different type.

For example:

1. First Level
  a. Second Level
    i. Third Level
      - Next Level

This option is turned on by default and is configurable via g:bullets_outline_levels so you can set what happens at each indentation level.

" Capitalization matters: all caps will make the symbol caps, lower = lower
" Standard bullets should include the marker symbol after 'std'
let g:bullets_outline_levels = ['ROM', 'ABC', 'num', 'abc', 'rom', 'std-', 'std*', 'std+']

There may still be some rough edges so if you encounter something please let us know in the issues section.
