Autoloading via composer

[hrach]

PHPStan IMO should not depend on composer autoloader of the project. It is not a direct (dev) dependency and no code depends on it. That's the main difference to other dev tools such as PHPUnit, the code is directly dependent on PHPUnit.

Would be great to use it as "tool" in CI:

composer create-project phpstan/phpstan --no-dev
./phpstan/phpstan analyse ./myproject

Yep, I'd like to to that really soon :)

By the way, currently PHPStan is also unusable as an external tool this way, composer global require phpstan/phpstan wouldn't work.

[ondrejmirtes]

Yep, it isn't, it will be an objective of a future release.

#50 is a proposition to fix that. We want to use phpstan as an external tool and we can do that with this PR.

This is now possible thanks to 3c71eda and 57f2ebe.
