Everything.me takes a while to load. This creates a particularly bad UX when the homescreen gets unloaded due to lack of memory and the user presses the home button. We should lazily load everything.me when the user visits the first page of the grid.

PR sent: https://github.com/mozilla-b2g/gaia/pull/5889 This lazily loads Everything.me when we pan to the left most page. The UX can definitely be improved here, it's not perfect. I left the default stubs ("Loading..." and something about being offline) in place for now. I'm not a good HTML/CSS guy, so if somebody else could handle the polish in a follow-up, that'd be great. Some sort of standard throbber [1] would be nice here. Judging from my profiling, this shaves at least ~200ms off of the Homescreen app's start time.

I'd actually expect it to save a lot more experience-wise in addition due to making it less likely that the homescreen will be evicted from memory - are you seeing that in your build with this patch? If so, that would be cool!

If so, that would be cool! Yes, yes I am. In fact, unless I pan to the everything.me page, the Homescreen app is now at least 7 megs slimmer.
