New docet:rundocs mojo

[eolivelli]

It would be very useful to have a "mojo" (Maven Goal) to start a Web Server and deploy the documentation package of the "current project"

[eolivelli]

Some ideas:

• let's use the "Sample App"
• bundle the War of the Sample App inside the JAR of the "plugin"
• add a new Mojo which:

• it unpackes the Sampe App War to a known directory (like target/docet-sample-app) (do not unpack if already unpacked)

• it starts a Jetty server (localhost, 8080, or configurable) and deploys the sample App

One problem to solve: the Sample App must have an automatic discovery mode of the current project (do not use "docet-packages.conf" or maybe just have a "docet-packages.conf" file with a default package based on '.' (current directory)
