refactor: add some dev files and black original code

Original server code has been moved to __init__ file, so we can
work on `lnbits` as a package.

+For developers
+==============
+
+LNbits uses [Flask](http://flask.pocoo.org/).  
+Feel free to contribute to the project.
+
+Application dependencies
+------------------------
+The application uses [Pipenv][pipenv] to manage Python packages.
+While in development, you will need to install all dependencies:
+
+    $ pipenv shell
+    $ pipenv install --dev
+
+Running the server
+------------------
+
+    $ flask run
+
+There is an environment variable called `FLASK_ENV` that has to be set to `development`
+if you want to run Flask in debug mode with autoreload
+
+Style guide
+-----------
+Tab size is 4 spaces. Maximum line length is 120. You should run `black` before commiting any change.
+
+    $ black lnbits
+
+[pipenv]: https://docs.pipenv.org/#install-pipenv-today
