Allow hook priority

[claudiu-cristea]

Problem

I would like to be able to determine the order in which some hooks are running (see also #113). As hooks are relying on Symfony event dispatcher, which supports priorities, this should be doable.

Proposal

Allow to pass an additional and optional priority integer value to the @hook annotation, for instance

@hook post-command commandname 300

Only some of the hooks rely on the event dispatcher. I was initially reluctant to add the complexity of priority, opting instead for pre and post phases. Would it make sense to use the event dispatcher all the time, and re-implement pre and post as shorthands for priority values? I don't know. I remain ambivalent.

Why do you need hook priority?
