* Support international format @tel@ URIs via linkrefs (link aliases.)
* Extend linkrefs to all available URI schemes in unrestricted mode.
* Reverted looser matching of list-like structures as it introduced problems in block-level elements that
  can legitimately have literals or other non-lists in them that are similar to textile's lists.
  See issue #65 for some examples.
* Fixed #61 which caused strong numeric strings at the start of a line to be turned into lists.
* Reverted auto-breaking in table cells as it introduced #71 (breaking lists within table cells).
