Merge pull request #7 from Blackshawk/master

Fixes, improvements, refactors, and Symfony console
Random fixes
Fixes and some doc blocks

Fixed a few naming bugs among resources that hadn't been encountered
yet. Wrote a few docblocks. Also added Monolog to the composer manifest.
Refactoring out hard dependencies

Added an option for specifying a specific queue from the command line
(such as heavy, light, etc.).

Refactored the base Sonido class so that most of its outside
dependencies are injected rather than created in the constructor. Also
made sure that Sonido is typehinted against interfaces, and not
specific classes.
