Editorconfig and Rebracer.xml

This is a redo of PR #350 

I submitted a PR with the Rebracer project to fix the issues I had with it. It has been merged and an update to the VSIX has been pushed as v1.2.

Before merging, I want to double check the diffs. This is the first time I have pushed an update to an already merged PR/Branch that has been reverted and the diff I am seeing creating the PR is not quite what I would expect. I will check the full diff once the PR is created.
