Title: Feature/support librato rails

A few internal changes to make integration with librato-rails a bit easier:
* Make log prefix configurable
* Support a pre-configured tracker object
* Break pid locking out of should_start checks
* Make it easier to overload user-agent version string
* Break out env-based config loading for easier management in subclasses
