* resolves dependencies by type hint or variable name
* simpler route.php
* implementation of https://github.com/owncloud/core/issues/12829

Generates and injects parameters automatically. You can now build full classes like

    $c->query('MyClassName')

without having to register it as a service. The resolved object's instance will be saved by using registerService. If a constructor parameter is not type hinted, the parameter name will be taken.

Therefore the following two implementations are identical:

    class Class1 { function __construct(MyClassName $class)
    class Class1 { function __construct($MyClassName)

This makes it possible to also inject primitive values such as strings, arrays etc.

In addition if the query could not be resolved, a `QueryException` is now thrown

Routes can now be returned as an array from `routes.php` and an `appinfo/application.php` is optional

fix copyright date in headers

fix indention

Otherwise the headers from `JSONResponse` are gone and the Content-Type of the response would be `text/html` instead of `application/json; charset=utf-8`. This leads to broken scripts since we set the `nosniff` tag, furthermore this is very bad from a security PoV.

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)`.

Those old classes have now non-static pendants and can be deprecated IMHO.

fix docstrings

adjust copyright date

another copyright date update

another header update

implement third headers argument, fix indention, fix docstrings

fix docstrings

- Remove not anymore existing parameters
- Fix typo

use fetch method instead of fetchRow because fetchRow is only an owncloud internal alias that exists purely for compability

remove methodannotationreader namespace

fix namespace for server container

fix tests

fail if with cors credentials header is set to true, implement a reusable preflighted cors method in the controller baseclass, make corsmiddleware private and register it for every request

remove uneeded  local in cors middleware registratio

dont uppercase cors to easily use it from routes

fix indention

comment fixes

explicitely set allow credentials header to false

dont depend on better controllers PR, fix that stuff later

split cors methods to be in a seperate controller for exposing apis

remove protected definitions from apicontroller since controller has it

register middleware as string to not force request to be instantiated too early and thus not having url parameters
