Clean up Symfony-related stuff after creating the project

This Pull Request "cleans" the installed project making the following changes:

  * Remove Symfony's `README.md` file and create a generic empty README.md
  * Remove all the Symfony's `UPGRADE*.md` files.
  * Remove the Symfony's `LICENSE.md` file.
  * Add the `.gitignore` file (and sort its entries)
  * Remove Symfony's `branch-alias` from `composer.json` file
  * Remove the `description` property from `composer.json` file
  * Put `proprietary` as the `license` in the `composer.json` file
