##### This pull request provides some cs and docblock fixes.

@fabpot The second commit of the two applies the docblock fixes you wanted, using https://github.com/FriendsOfPHP/PHP-CS-Fixer/pull/887. I made 3 or 4 minor manual changes because people had put bulleted lists in the "short description" which is not allowed, so we were ending up with colons followed by full stops. I've moved those lists to be part of a "long description".

Especially if deprecation notices are silenced on the main php instance, we should also silence them in the insulated Client

The new --prefer-lowest matrix line fails randomly with ["Killed" message](http://docs.travis-ci.com/user/common-build-problems/#My-build-script-is-killed-without-any-error).
Lets try reducing concurrency on this one.
The matrix is also reordered so that the slowest lines are started first.
