I keep getting logged out

[sbrl]

If I'm inactive for a time (or I've just been working on a page for a while), then I get logged out when I next reload the page.

We should allow the user to stay logged in for at least 24 hours.

It seems that there are multiple possible causes for this bug:

• The session cookie could be expiring (See this SO question)
• The session files could be getting deleted by PHP.

Again, there are multiple solutions:

• Set a longer expiry date on the session cookie.
• Make sure that PHP is not deleting the session files early.
• Add a JS snippet to every page that pings the server every 5 minutes or so to keep the session from expiring. We would need to check if setTimeout measures real time, or whether the timer gets stopped when a page is not focused, as JS get's slowed down / paused when a tab is not active in Chrome.

It look like it's the cookie thing causing this problem!
