WIP: [#364] Setup and play around with IntelliJ plugin

[beikov]

Description

These are the first steps to an IntelliJ plugin that gives some level of support for entity views within the IDE. At least the project setup and build is done now and can be tested. Now comes the hard part, actually implementing some stuff.

I played around with a few features

• An entity view edit dialog to change/add mappings in a bulk fashion
• A generation action that can generate entity view attributes for entity attributes
• JPQLNext parser integration for syntax highlighting and autocompletion in entity view @Mapping

This is all still very rough and at some point I will continue working on it. Maybe someone wants to get this done earlier and takes this over? :)
