New minor release 0.0.7:

* Added metadata file to handle hardcoded things in the orignal game.
* Read the correct sky for each level from metadata.
* Read animation frames from metadata.
* Fixed build issues on newest compiler and libraries.
* A bunch of lighting fixes that make it truer to the original.
* Use new rust 0.12 features: lifetime elision & slicing syntax.
* Replace broken wad name handling with a type WadName. Much cleaner WAD code
  as a result.
