Fix installation with incenteev script + update vendors

Hello,
For my first installation of ClubMaster, I had an error running `composer install` just after cloning the repository. This PR adds "incenteev/composer-parameter-handler" to the project to ease the installation by asking parameter values.

I've also updated the vendors:
```
