`yii\web\Request::cookieValidationKey` is now automatically generated by the installation script for the basic and advanced application templates

Fixes #1597: Added `enableAutoLogin` to basic and advanced application templates so "remember me" now works properly

Small edit for consistency with /apps/advanced/backend/config/main.php. Sorry, my OCD kicked in.

- Turned on CSRF validation by default.
- Added access control for login, signup and logout for frontend application.
- Added access control for login, logout and index for backend application.
- YII_ENV is now defined for all applications.
- No trace is writted to logs if debug is turned off.
- Added default error view for frontend and backend.
- In frontend application captcha will always ask for "testme" if YII_ENV is defined as "test".

- update composer json to chosse right path
- set vendorPath in application config if not default

Added console command support to the bootstrap app.

removed app template from framework folder.

Appended newlines to every PHP document that did not have a newline as the last character in the file.
