Added fix for timeout on autorecover [B:1361]

[droberts-ctrlo]

• Added a record identifier to the session
• Removed clear from the save button code (we want the data cleared on successful submission)
• Created a new Alert component that checks for the data attribute that contains the record ID, and clears the data using that if it's present
• Added data attribute to the message_center view

Despite me saying that this should go in the alert, I think that actually on reflection it can be kept separate (I was originally thinking that using the alert was the only way of keeping it persistent across requests). I think that actually you should set a session variable on successful submit (as you are doing), but instead it should be a more generic variable (e.g. actions_for_page). This would then be rendered as data in the body of the page (or similar) and passed using the before_template hook. Then, the Javascript should be updated to look for those particular data items and act accordingly. This could potentially be used for other actions we need the Javascript to do on page load.

As such, I think it should be rendered for all pages, not just the data page.

Finally, having seen the complicated code needed for removing all the required fields, I am wondering if we can change the data structure of the local storage, having a way of grouping all fields together for one instance, so that they can be easily deleted rather than needing to loop through and find each one.

Thanks Dave, just some minor comments for consideration
