Enable per project debug and refactor GitApp

You can now run tests in debug mode (does not destroy app after test is run) on individual tests via specifying `debug: true` when initializing a Hatchet app like so:

    Hatchet::GitApp.new(debug: true, "repos/rails3/codetriage)

You can turn on debug globally by running tests with the environment variable `HATCHET_DEBUG=true`.
Allow configurable process timeouts

If you know something is going to take a long time, just set a longer timeout.
