F/sniff rollups

[beporter]

Integrates corrections for updated sniff rules. Specifically:

• Multi-line arrays should now include a trailing comma by default.
• File and class doc blocks are a bit more consistent (probably still needs work.)
• Migration template files are included, so bin/cake bake migration --theme LoadsysTheme ... is now recommended. This will produce files that use tabs, have doc blocks and place open braces on the same line.

This work hasn't been tested yet. I need to coordinate with work in the skeleton to:

1. Integrate this branch of the LoadsysTheme into the skeleton somehow.
2. Bake a project from the skeleton "in-progress".
3. Bake example migrations and code in the spawned project.
4. Run the code-sniffer and unit tests on the resulting baked code.

Also, it would be cool if there was a way to make the default BakeShell someone "know" to use --theme LoadsysTheme "by default" without it having to be specified. Seems like this should be possible, but it requires investigation. I'd like to do this via an Event hook or Configure so it can be done (and customized) on a per-project basis, instead of depending on a wrapper bash script.

The commits are kind of messy, but the work is all here. This branch needs to be merged and a 1.1.0 versions tagged and released on Packagist before loadsys/CakePHP-Skeleton#168 can be merged and tagged safely.
