zend-json required only as dev dependency

[reinfi]

Hey there,

why is zend-json only required as dev dependency, although the JsonModel in this package has a dependency on it?

Could it be moved to normal dependencies?

It is only a soft dependency and therefore it is included in the suggest section of the composer file.

zend-view/composer.json

Line 53 in 651621d

"zendframework/zend-json": "Zend\\Json component",

Or with other words: zend-json is not strictly required.

I found a problem: the JsonModel may be optional, but zend-json is also used in the Json view helper and in the AbstractHtmlElement:

https://github.com/zendframework/zend-view/blob/master/src/Helper/Json.php

zend-view/src/Helper/AbstractHtmlElement.php

Line 79 in 651621d

$val = \Zend\Json\Json::encode($val);

I've created PR #169 for it
