Introduce src/gen/java for generated sources
Previously, sources generated from the serpent antlr grammar in ethereumj-core/src/main/antlr4 were output into the build/generated-src directory by default. This worked from the command line without issue, but caused issues within IDEA, because the entirety of the 'build' directory is excluded from compilation by default when working with a Gradle-based project in IDEA. This change simplifies the arrangement by writing these antlr-generated sources to the src/gen/java. A .gitignore file has been added to ensure that transient source files don't accidentally get checked in. A readme file has been added to explain the situation to the uninitiated.

Use IDEA 14 or better and import project based on Gradle sources.

Note that in order to build the project without errors in IDEA, you will need to run `gradle antlr4` manually.

the `src/main/antlr4` directory using the `gradle antlr4` task. Sources are

output here instead of the typical `build/generated-src` output directory in

`build.gradle` for details.
