Address #1902: Converts example/flaskr to have a setup.py (#1945)

Browse source 
* Converts example/flaskr to have a setup.py

Makes the flaskr app easier to run, ex. workflow:
- pip install --editable .
- export FLASK_APP=flaskr.flaskr
- flask initdb
- flask run

Testing is also easier now:
- python setup.py test

* Fixed an import error in flaskr/tests

- the statement `import flaskr` caused errors in python3
- `from . import flaskr` fixes the issue in 2.7.11 and 3.5.1

* Better project structure and updates the docs

- Re-factors *flaskr*'s project structure a bit
- Updates docs to make sense with the new structure
  - Adds a new step about installing Flask apps with setuptools
  - Switches first-person style writing to second-person (reads better IMO)
  - Adds segments in *testing.rst* for running tests with setuptools

* Remove __init__.py from tests

- py.test recommends not using __init__.py

* Fix testing import errors

Now it is time to start working on the templates. As you may have
noticed, if you make requests with the app running, you will get
an exception that Flask cannot find the templates. The templates
are using `Jinja2`_ syntax and have autoescaping enabled by
default. This means that unless you mark a value in the code with
:class:`~flask.Markup` or with the ``|safe`` filter in the template,
Jinja2 will ensure that special characters such as ``<`` or ``>`` are
