B/logic fix

Provides a new means for automatically running a command inside of vagrant when it is found to be available. For example,

* Running `bin/run-tests` from your project root on your host machine will actually run `vagrant ssh; cd /vagrant; Console/cake test app All --configuration=Config/phpunit.xml`
* Running `bin/run-tests` from inside vagrant already only executes `Console/cake test app All --configuration=Config/phpunit.xml`

`run-tests` is currently the only script in the package that implements this. Still to do are:

* run-codesniffer
* docs-generate
* _?_ (Target commands that are typically run by hand as shortcuts from outside the vm.)
