Keeping an eye on PHP 5.6

PHP 5.6 still alpha, but we can check if our code will break over there. Seems we have one incompatible thing so far. :)

Updated Respect\Foundation
hhvm RecursiveTreeIterator support

This code is from the PHP source itself. It's required to run
Respect\Validation on hhvm, which lacks the class.

By adding it to the library folder, it's loaded automatically
by our testing routines.

Further documentation should be written, but only after a stable
build for hhvm appears on Travis.
PHP 5.6 working, hhvm on testing
Add scrutinizer badges to README.

Also removes the unstable build badge, which is kind of redundant since
we will always respect the pattern of keeping the `master` branch stable
enough to be used.

Two Scrutinizer badges were added: code coverage and code quality.

Travis changed to report code coverage to Scrutinizer.
Removes new line from beggining of file.

Since this is considered output by PHP and could harm the output buffer
for requests that will send headers after this.

Nasty bug.
