Handle quotes in parsing

[icmx]

comicparse library should handle incorrect quotes in a following way:

• ' and " should became “, but only if they're surrounding one or more words, i.e. like this:
  • test test's test -> do nothing
  • test 'test' test -> test “test“ test
  • test 'test test' test -> test “test test“ test
  • test 'test test' -> test “test test“ test
• Repeated “ should be trimmed into one, like ““““what it this““ -> “what it this“
