some welcome fixes related to the auto-hinter:

- removed a stupid memory leak

  - fixed the weird metrics hinting (the horizontal edges were used,
    instead of the vertical one, to compute the metrics adjustments,
    silly, silly, silly).

there is still some bugs that I'm looking at though, but we're
very near the release..
