Appcache, and www-built

Hi,
basically what there is in www-built is what is generated after doing:

volo build
volo appcache

If replaced in http://openappchat.jit.su/ this should work
For making apps installable, an appcache is needed

This can be tested in desktop:

Let me know if it works in iOS
