v0.0.7

This release of unshrtn shortens the lines of code (pun intended) quite a bit because URL resolution and metadata extraction has been pulled into to a separate Node library named metaweb. Unsrhrtn just provides the HTTP microservice and caches responses in LevelDB.

As a result unshrtn will now extract basic Facebook and Twitter metadata from pages such as images, description, keywords:
