Vim-LaTeX-Suite updates

- Reduced cursor jumps when doing LaTeX_Build.
- Better wrapping & display: no textwidth, we can do it with gq if
  needed.  Some visual cues for wrapped lines.
- :set autowrite instead of :write.
Cleaned up some vim key mappings

- <C-\>KEY only does :setlocal to touch local option, whereas
  <C-\><C-G>KEY does :set for global options.
- <C-\>KEY is for togglable things, while <Space>KEY is for
  non-togglables.
- <Space>d to diffoff + restore color scheme.

Better LaTeX formatting in Vim with formatprg

  keep each sentence in a whole line.

  but okay for most cases.  Can get used to d<CR>, d- instead)
- Cute unicode character linebreak/wrap lines.
