- README fixed to accurately represent padding for < and >

- h token type refactored and is much simpler

- h padding pads on the correct side for < and >
    - it was backwards

- now all getters expect `(c, winnr)` and are passed that in lyne#pre and
  lyne#post
    - before, the lyne#pre and lyne#post were passing nothing, which was
      inconsistent

- adding padding in lyne#statusline was simplified by using `l:pad` and
  accessing either 0 or 1, which is created from a string comparison
