plugings: use vim-pandoc instead of pencil

* Uses vim-pandoc instead of pencil because it handles better the hard
  wrap.
* Adds map binding to use hard or soft wrap and to enable or disable
  autoformat (vim-pandoc).
* Adds configuration for specific text width and column lines for git
  commit messages.
* Set spelllang to English for git commit messages.
