Local storage

[JangoSteve]

This might overlap with the offline mode ticket #1, so not sure if this needs its own page or not. But it could work differently in that we could allow visitors to type some information or something like that, and then save it to local storage, so when they come back later, it's still there.

But I'm sure we could probably come up with something with a bit more pizazz.

It should be a demo that accomplishes the following:

• Ideally it'd be something that requires saving a lot more data than a cookie, so we can show how it's different.
• It should be something only the user would put in and remember, so that it's clear we're not fetching the data from a 3rd-party.
• It shouldn't overlap too much with any of the other demos, in order to avoid confusion as to what's being demo'd.

We may need to think about this a bit.

My idea for a simple shopping list app for #1 could cover this issue as well.
