Provide method to stop Gradle Build

When running a Gradle build there is no way to stop the build (the stop button is disabled in the Gradle Build console). This can prove to be problematic when the task is something like running a server (i.e. the spring-security's casServer task) which is intended to run until the process is stopped. I tried opening the Progress view and clicking the stop button there, but that does not seem to work. At this point the workaround I have is to kill the process.
