POM: include imagej-scripting component
POM: include imagej-scripting component

This component does three things:

1) It unions the SciJava script language components we desire to include
   with ImageJ, so they no longer need to be declared individually.

2) It provides a collection of tutorial scripts for the Script Editor.

3) It includes any image-specific script-related functionality on the
   Java side. For example, if a SciJava converter were needed between a
   Jython type and an ImgLib2 type, this would the place to put it.
   (We thought we were going to create such a thing recently, but it
   turned out to be unnecessary, at least for now.)
