PHPUnit 7 support

[michalbundyra]

Any plan of adding PHPUnit 7 support? Thanks !

Yes, this would be helpful for some upgrades we're working on right now.

I have created a fork which supports PHPUnit 7. I couldn't solve the problem in a nice way (at least not easily), but it works. Feel free to use it if you really need PHPUnit 7 support now.

Sorry guys for not acting earlier. Does any of you want to take over this project. See php-mock/php-mock#20
