Configuration option to change id for #app and #page-wrap

[valeriosillari]

Hello, just wondering if there is a way to change the default IDs used for the elements, as described in the documentation.

I would like to get an option to set this ID in custom way, because I have already another component using "page-wrap" and I got some conflicts.

I think this is more a feature request, but it would be nice to have (I guess it's not possibile yet).

by the way: awesome project :)
