Replace Chosen by Select2

[agilare]

Chosen is currently used in La décadanse in gererEvenement, ajouterDescription, ajouterEvenement, ajouterLieu, ajouterPersonne, copierEvenement, inscription mostly to easily select with autocomplete a place or an organisation associated to an event, place, user, etc. Chosen and Select2 are similar but the last one has more features and is more maintained. Select2 would be useful particularly in event add form, in section allowing to choose the place of the event; if place not in list user would be able to add a custom name with tagging.

• [ ] select2 main config
• [ ] event-add : lieu, localité, orgnisateurs
• [ ] registration : lieu, orga
• [ ] user : lieu, orga
• [ ] lieu : orga, localité
• [ ] admin event : lieu, localité, orga

Chosen is announced as deprecated since January 2020

In addition, Chosen is disabled on iPhone, iPod Touch, and Android mobile devices which explains why some users adding events doesn't choose a venue existing in the "Nom du lieu :" list and find easier to write the informations in the fields below. I've found other alternatives to Chosen like https://choices-js.github.io/Choices/ and https://tom-select.js.org/
