Create a Gradle task to run the test server (#192)

* Create a Gradle task to run the test server

As an artifact of the old build system, the test server relies on having
the built registrar_(bin|dbg)*(\.css)?.js in place (see ConsoleUiAction
among others). As a result, we create a Gradle task that puts those
files into the correct, readable, location before running the test
server.

* Depend on assemble rather than build

* refactor gitignores
