Composer: Update PHPCS to 1.5.2.
Vim: Add fuzzy#CompleteFuzzy.

This will eventually turn into a plug-in for more powerful and context-
aware completions. E.g., completing variable or function names using
fuzzy text-matching:

    function helloWorld() { }
    hw<Tab>  " will complete as helloWorld

For PHP files, I quite often have boilerplate code which I want to
reduce the typing for. E.g., creating a type-hinted property:

    p $hello array<Tab>

      |
      V

    /**
     * @var array
     */
    private $hello;
