Create new stable version

[robertfausk]

Can you please tag a new release? (Because of checkstyle support and so on...)
Thanks in advance :)

Same here.

@JakubOnderka I vaguely recall you mentioned several prerequisite you'd like to match before cutting a new version (it was rather long time ago, though); is there anything outstanding? If there is, do you need a hand with anything? I'll be glad to help to stop pinpointing my composer.lock to a specific commit :)

+1, especially for #125 as phan will fail analysis on projects that use this project.
