Add functions to modify cookies to response class

Currently there is no AppFramework way to modify cookies, which makes it unusable for quite some use-cases or results in untestable code.

This PR adds some basic functionalities to add and invalidate cookies.

Usage:
```php
$response = new TemplateResponse(...);
$response->addCookie('foo', 'bar');
$response->invalidateCookie('foo');
$response->addCookie('bar', 'foo', new \DateTime('2015-01-01 00:00'));
```

Existing cookies can be accessed with the AppFramework using `$this->request->getCookie($name)`.
Use server container
Remove redundant code
Pass \OC::$WEBROOT to the ctr
Move share interfaces to own files so they can be autoloaded
Move iHomeStorage to own file
Move NaturalSort_DefaultCollator to its own file
Move registration of core preview providers to preview

So the class files only have class code and don't execute code
Limit blacklist to php files

During performance optimization I have discovered that the installer scans all files for the blacklisted words. This greatly impacts speed on lower end devices such as the raspberry pie. This commit limits it to PHP files which seems to achieve the desired effect. 

I have used the --include option to achieve this, see http://stackoverflow.com/questions/1987926/how-do-i-grep-recursively
