Add php-cs-fixer
Added ./scripts/php-cs-fixer
http://cs.sensiolabs.org/.
We can use it to keep php style consistent.
A nice command to show what it would do (and return non-zero exit code):
./scripts/php-cs-fixer fix app/bezirk --dry-run --diff --verbose
To fix all the fixable stuff:
./scripts/php-cs-fixer fix app/bezirk
By default it is using "symfony" standard, which seems a good option.
