fix(ionNavButtons): multiple ionNavButtons elements align correctly

Fixes #930

Uses a `<span>` now for each set buttons in the navbar, instead of a
`<div>`.  This means that the buttons will align correctly instead of
creating new lines for each set of buttons.
fix(scss): make tabs,header,footer aligned right with statusbar

Addresses #943

Before: we offset the has-header and other classes by 20px if a status
bar existed.

After: we simply offset the body by 20px if a status bar exists. This
makes the other classes automatically offset themselves.
