Added link to ProvisionQL

Check out [ProvisionQL](https://github.com/ealeksandrov/ProvisionQL) - open-source, based on [Provisioning](https://github.com/chockenberry/Provisioning).

Inspired by number of existing alternatives, the goal of this project is to provide clean, reliable, current and open-source Quick Look plugin for iOS & OSX developers.

Thumbnails will show app icon for `.ipa` or expiring status and device count for `.mobileprovision`. Quick look preview will give a lot of information, including UUIDs, devices, certificates and much more.

Supporting file types:

* `.ipa` - iOS packaged application (both Xcode generated and from iTunes)
* `.app` - iOS application bundle
* `.mobileprovision` - iOS provisioning profile
* `.provisionprofile` - OSX provisioning profile
