Version 1.4.0 - Default ignore file, bug fixes aplenty

• Feature: Read intraconv.toml by default when no ignore file is given (#36).
• Fix: Ignore primitive.Type.html links since transforming them is wrong most
  of the time (#35).
• Fix: Properly handle directories when they are given explicitly in a
  workspace (no issue).
• Fix: Correctly detect ignored links for long links (#38).
• Fix: use --ignore-file instead of ----ignore-file (#37).
