Suggestion to replace PinkySwear to Zousan

[paulocoghi]

PinkySwear is (probably) not maintained anymore.

The last update (2014) uses Mocha 1.21.5, that uses Jade (instead of Pug), Graceful-fs 2.0.3 (that will fail on node releases >= v7.0) and a version of MiniMatch that has security vulnerabilities.

I really like Zousan* but there are also many other implementations and I don't want to be unfair.

*Because it has no dependencies and still small, works everywhere (browser, node, mobile, etc), it's recent and really well maintained, Promise A+ 1.1 compliant, well documented and incredibly fast.

I feel that I don't have enough knowledge to make this replacement in Qwest myself. But, if you want, I am available to learn and do this. :)

Good idea, I should update that with Zousan. I need to analyze the current PinkySwear implementation first, because qwest is using some specific PinkySwear options (like Promise prototyping).

Since qwest need to be refactored, I plan this for the v5 release ;)
