Update SublimeLinter:

- Add Frog as pre-defined global
- 4 spaces instead 2 for indentation
- Remove 'use strict' enforcement
- Enforce use of curlys for blocks
- Add `es3` option for enforcing IE8 compatibility
- Prohibit native object extension (i.e. Object, Array, Date, etc)
Remove Achieve, Mylibrary and Me from pre-defined globals list, on the basis
that there should technically be an entry for **every** app in the list, not
just those ones.  Need to think of a way to cover this.
