Formatting/Refactor (Task Model & Persistence Goodies)

Primarily formatting files (via PHPStorm magic) to adhere to [PSR-2](http://www.php-fig.org/psr/psr-2/). Includes some minor refactoring etc... see individual commits for details.

*Take note of the separation of changes into logical commits* w/ clear commit summaries (the first line) and useful commit messages (the rest of the commit message after the first line). 

5e888d0 - Purely formatting (PSR-1/PSR-2). 99% whitespace. Renames GetID->getId
5f44d6d - Adds $hardcoded_tasks (PHP) and simple iteration to display them.
111587f - Task - Implements JsonSerializable. Adds "fillable" overrides __set.

This makes it much easier for discussion and code reviews (before merging) and especially valuable in the future when reviewing history to figure out WTF was this person thinking (i.e. Why is this file the way it is?, Why were these changes made?, etc...).
