Feature/testing

[drewbanin]

This is the first cut of testing -- views are created to ensure that

1. model sql is valid
2. all referenced tables exist
3. all referenced columns in tables exist

Testings is pretty much just compilation + running sql w/ different CREATE templates and error handling. Lots of the changes below are tweaks to output, or refactoring to share code between compile, run, and test tasks

I set up dbt and everything appears to be in good order, but when I attempt to compile, I get this:

(venv)vagrant@precise64:/vagrant/zendesk$ dbt compile
Traceback (most recent call last):
  File "/usr/local/bin/dbt", line 7, in <module>
    execfile(__file__)
  File "/vagrant/scripts/dbt", line 8, in <module>
    dbt.main.main(sys.argv[1:])
  File "/vagrant/dbt/main.py", line 52, in main
    proj = project.read_project('dbt_project.yml').with_profiles(parsed.profile)
  File "/vagrant/dbt/project.py", line 115, in read_project
    proj.validate()
  File "/vagrant/dbt/project.py", line 81, in validate
    target_cfg = self.run_environment()
  File "/vagrant/dbt/project.py", line 66, in run_environment
    return self.cfg['outputs'][target_name]
KeyError: 'default'

I'm in a clean VM, set up dbt via python setup.py develop. I'm using the zendesk repo as an example, and compilation works perfectly fine in dbt master.

Not sure what's going on here but it's blocking me from testing out other elements of this PR...

@jthandy did you set up your ~/.dbt/profiles.yml file?
