Title: Fix code sample indentation in arbre documentation

The tab-style indentation in [`docs/12-arbre-components.md`](http://activeadmin.info/docs/12-arbre-components.html) makes for not-so-pretty code samples.

This pull-request changes tabs in to 2 spaces. Except for the first tab, which needs to be 4 spaces for code samples.
