BasicSetup and ModuleUtils migrated from jPOS-EE

jPOS-EE has a feature implemented by @vsalaman that allows us to extract
configuration files from all the installed jars and install them into a
standard Q2 working directory.

We thought non jPOS-EE applications could benefit from this feature so
we are migrating it to jPOS.
BasicSetup renamed to Install
new installApp target taken from jPOS-template

With this new target, we can:

  gradle installApp && build/install/jpos/bin/q2

to run a jPOS instance inside the jPOS build
(useful for debugging purposes).
