format objc.

This is part of unforking JSQMVC, but I'm only reformatting files
otherwise changed rather than reformatting the entire project for git
sanity.

This is intentionally a second commit so we can separate formatting
changes from code changes

* brace should drop after method definition (this is common across
  almost all objc projects, and allows you to quickly differentiate
  multi-line method signatures from their implementation.
* aligning consecutive assignments ongoingly muddies git history
