Update for new PHP packages from Homebrew

[ikari7789]

Homebrew decided to change the way that they manage PHP. It has some big differences, especially in the package names.

See https://github.com/Homebrew/homebrew-php/issues/4721

This should probably be released as v2.0.

@ikari7789 thanks for your help making brew php switcher better. I am going to merge this now and as suggested release version 2.0

[ikari7789]

Thanks a lot! I have fixes for some other issues cooking as well, but may take me a day or two to find time to clean it up.

Sorry if I will look stupid, but now there is php@7.1.. okei.. but how to install redis, php extension (before it was php71-redis) for this php@7.1 version? And I think that some more extensions was removed with forumulaes also .. :( em.. and php (version 7.2) not suitable for my projects.. :/ also I dont see php-fpm included.. which earlier was like in /usr/local/opt/php71/homebrew.mxcl.php71.plist

@pauliuslukosiunas because redis is language agnostic (see https://redis.io/clients) therefore its not tied to php.
To get redis installed I would assume its a simple brew install redis and then link the module in the php.ini
When I say I assume this is because I myself don't use redis so please feel free to try and write back your discoveries.
