Title:
  Fix issues reported by valgrind

Status in Enblend:
  Fix Committed

Bug description:
  Hi everyone,

  I ran enblend under valgrind which reported several issues.

  The first one is a simple missing initialization.

  The other ones are mostly about bad usage of boost::scoped_ptr<>. I have two 
  different approaches to fix this:

  1. Directly write into std::string buffer instead of using a temporary char[] 
  buffer. This is guaranteed behavior by C++11, see e.g.
  http://herbsutter.com/2008/04/07/cringe-not-vectors-are-guaranteed-to-be-contiguous/#comment-483

  2. Use a boost::tokenizer. As it does not need a char[] buffer, different to
  strtok, no need to allocate one. This has the nice side effect to get rid
  of the homegrown enblend::strtoken_r tokenizer.

  Kind regards,

  Stefan
