Fatal Errors with latest update and PHP 7.0+

[matt-usurp]

I am having issues when running this on my docker box with the latest changes.

I find it strange that this gets past the build, but does the build ever test through the Console\Application class? This might want to be something we look in too if not?

Fatal error: Uncaught TypeError: ini_set() expects parameter 2 to be string, boolean given in /src/PHPFormatter/Console/Application.php on line 35

TypeError: ini_set() expects parameter 2 to be string, boolean given in /src/PHPFormatter/Console/Application.php on line 35

Call Stack:

    0.0180     863312   3. ini_set() /src/PHPFormatter/Console/Application.php:35

The culprit looks to be here as described in the above stack and in the documentation:
https://github.com/mmoreram/php-formatter/blob/v1.3.1/src/PHPFormatter/Console/Application.php#L34-L37

And looks like PHP documentation has been updated for PHP 7.0.
string ini_set(string $varname , string $newvalue)

@matt-usurp Thanks!

#31

This is the alive probe that strict_types in PHP^7.0 is a big big change in this language :)

Can you please check the PR?

Thanks!^^
