call to IP server not docker
1. Ace editor sends email regularly to engage gmail address for logs of students' work
2. Help form added to the create serious game page for email error log + CF to me (uws)
Change call to web service IP instead of "docker"
Back to without help form => doesn't work on server
Button to submit config file is disabled when errors are found in the DSL
Interface has been changed a bit to facilitate create of new pages (banner2 added by default except main page, alert messages added to layout...)
Fig modified to have a faster website
Added - a button to save the current config file and another to load a saved .txt into the editor
