Menus: Nav menu locations should not be integers. 

When nav menu location slugs are integers, some hard to debug results can occur. `register_nav_menus()` utilizes `array_merge()` which renumbers numeric indexes, starting from 0. Because of this, numeric menu locations will almost always be changed.

This change introduces a `_doing_it_wrong()` notice to inform developers that nav menu locations should always be strings.
