JWT 1.0.1 (for Vapor 1)

Fixed:

• Crashes on Linux with Swift 3.1 (#41 -> #44)

---

Upgrading is highly recommended for Linux deployments.

To upgrade, do one of the following:

• Use swift package update; or
• Use vapor update (Toolbox ≥ 1.0.9 required); or
• Perform a complete clean (including Package.pins if exists) and build/regenerate again.
