v0.2.0

• Feature: Packages can now also be cloned from any git URLs (#9), like this:

$ phar-composer build https://github.com/clue/phar-composer.git

The above will clone the repository and check out the default branch.
You can also specify either a tag or branch name very similar to how composer works:

$ phar-composer build https://github.com/clue/phar-composer.git:dev-master
