Framework Dependency Handling (Fix #115)

Per #115, this lists out all packages for the Framework we're actually depending on.  Since we're using so much of it, Composer is still installing the full Framework, but this better gauges what we are actually using.  I've also removed the use of the Framework's Event and Log packages (Event was actually unused totally aside from loading the dispatcher and Log replaced with our using Monolog).

Other dependencies are updated as well with the `composer update`
