Fixed typo in filename.
use Promise instead of Future in java example
replaced folder app/views/html/... by app/views/... in "Improving the Layout"

Seems like this is a typo. The folder for projects/group.scala.html, projects/item.scala.html, and main.scala.html should be just views instead of views/html.

At least in my case the tutorial didn't work when putting, for example, the projects folder into app/views/html.
(Doing the tutorial with play! 2.1.2 (using Java 1.6.0_51 and Scala 2.10.0)).
Improved plugins docs

Improved the plugins docs to make it clear that plugins must declare a

the error message that is thrown when they don't.
