Chat application based on Netflux

The application is available on coast-team.github.io/netflux-chat.

The application is divised in three parts :

• chat display, each message is mentionned with its author ;
• users display, each user appears here, the editable one is you, and the + button displays the id of the user ;
• chat input, you can send pictures with their URL, and links. You can use markdown.

Some specifications about the application :

• you can let the ws input empty, there is a default one ;
• : triggers an emoji auto-complete, use tab to add the completion ;
• /w on start of your message triggers a private message auto-complete, use tab to add the completion ;
• the + button with caret makes easy to add a picture (including .gif) or a link if you don't know the markdown syntax ;
• you can write multi-line messages using shift + enter to create a new line.

fix soon : when the chat's creator leaves the application, the application is closed for other users.
