Add helper task for extra setup after opening in IntelliJ IDEA

This task serves a similar role to the "afterEclipseBuildshipImport"
task used with Eclipse.  It should only be necessary to build this
task once:  in a freshly checked-out tree, just after opening it for
the first time in IntelliJ IDEA.

Ideally this extra setup task would be triggered automatically using
the "Tasks Activation" feature of IntelliJ IDEA's Gradle support.
Unfortunately, "Tasks Activation" settings are recorded in
".idea/workspace.xml", which is used for non-revision-tracked personal
settings.
