XXX: Use updated 2.2.2 linter with editorconfig-maven-plugin 0.1.3 for the fixed .idea default exclude

[inkarkat]

Python development is hampered by EditorConfig complaining about violations in .idea directories when they are not directly in the repo root.
This got fixed in ec4j/editorconfig-linters#25, but no editorconfig-maven-plugin has been released; only the dependencies themselves.
