As part of moving the FX 11-dev/rt repo from hg.openjdk.java.net to github.com, we will enable the Skara tools. This requires a `.jcheck/conf` file be checked in to the repo.

In order to allow developers to continue to use the existing Mercurial jcheck locally, this will be pushed as part of the transition to git + Skara.

The existing .jcheck/conf from jfx mainline will be used as the starting point, and will likely need no changes.
