Add a "coreDev" gradle target (#667)

* Add a "buildFmt" gradle target

This does the same thing as the automatic Java build target, except instead of
failing if the code formatting isn't correct, it just automatically reformats as
necessary and continues on.

* Remove unnecessary mustRunAfters

* Make it run tests too, and add :taskTree task

* Rename task to coreDev and remove run afters

* Add task tree dependency

* Actually that may not be necessary
