git gutter, whitespace handling
git gutter, whitespace handling

Why:
To add white space handling:
- remove trailing whitespaces in a file `<leader>c`
- Show all whitespaces
- add gitgutter support

This change addresses the need by:
Add vim-gitgutter plugin, add
`set list` to show whitespaces and
create a mapping to remove all trailing
whitespaces
