Real URLs without backend - proposal

Hi! I found myself building a single page app where most of the pages are available only after authentication, and therefore not visible for crawlers. Also I don't care about SEO much. Actually don't care about SEO at all.

Anyways. I used the history api setting in the router and saw it failing in IEs. That's a pity, so I added an option that would allow lazy people like me to have their routes working no matter if they have backend or not. Sounds neat.

What do you think?
