Add-on developers, please consider PHP 7

Permalink
It seems that many add-ons currently available for Concrete5 5.7 don't work with PHP 7, causing fatal errors that could make the whole site inaccessible.

So far i have found two methods that only need small modifications in order to work with PHP 7 (while there might be some more):

path: packages/[name_of_package]/blocks/[name_of_block]/controller.php

public function validate()
should be:
public function validate($args)


public function registerViewAssets()
should be:
public function registerViewAssets($outputContent = '')
