3.0 Cake Bake New Look #2 - App Skeleton Files

App Skeleton files for https://github.com/cakephp/cakephp/pull/4752
**all** files have a newline at the end of the file. 

It's a part of [the fig standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md#22-files) and part of [CakePHP's code standard](https://github.com/cakephp/cakephp-codesniffer/blob/master/CakePHP/ruleset.xml#L27).

Part of the reason for this rule is to prevent pointless whitespace changes caused by the OS of whoever edited the file last.
