feat: Reference demo: Tabs with individual sidemenus

[mpaland]

Type: feat

Ionic Version: 2.x

Platform: all

I've seen and read this requirement so often (in the forum, too):
A reference implementation using a tabbed interface where every tab has its own sidemenu.
It's like a combination out of the ionic-starter-tabs and ionic-starter-sidemenu.
Perhaps you can consider creating a v2 reference ionic-starter-tabs-sidemenu app.
Would be really great for a lot of folks!
