• Documentation improvements (gh#241, gh#254, gh#283, gh#298, gh#312, gh#327)
  
• Added .runtime.inline_auto_include property (gh#226, gh#328)
  
• xs_ok in Test::Alien will now keep temporary generated files on failure
  by default. You can override this behavior using TEST_ALIEN_ALWAYS_KEEP
  (gh#315, gh#326)
  
• Added TEST_ALIEN_ALIENS_MISSING environment variable to remove warning
  in Test::Alien when you use some tools without first calling alien_ok
  (gh#326)
