+- Update jet parser to v5.0.2, closes [#1551](https://github.com/kataras/iris/issues/1551). It contains two breaking changes by its author:
     - Relative paths on `extends, import, include...` tmpl functions, e.g. `{{extends "../layouts/application.jet"}}` instead of `layouts/application.jet`
     - the new [jet.Ranger](https://github.com/CloudyKit/jet/pull/165) interface now requires a `ProvidesIndex() bool` method too
     - Example has been [updated](https://github.com/kataras/iris/tree/master/_examples/view/template_jet_0)
