Consider widen Composer's constraints for PHPStan

[Aerendir]

Currently PHPStan is constrained at version 0.11.6 but the latest patch version is 0.11.8.

This causes me to not be able to update to the latest patched version.

Is it possible to use a constraint like phpstan:~0.11.6? Or may this cause a BC that may require more deep refactorings in Rector (so, too much work for the moment and not as easy as changing the version constraint).

For reference: Tilde version range

In past (around 2-5 months ago) it caused BC break issues, PHPStan was change a lot. But maybe now it's more stable.

So we can give it a try, Travis is already testing the lowest deps:

rector/.travis.yml

Line 9 in a69d08b

env: COMPOSER_FLAGS="--prefer-lowest"

Try PR and let's see if tests pass

Ok, I'll do it ASAP... Currently I'm applying Rector to an existing app...
