Proposed one minor change to .clang-format file (it might require overall acceptance by most/all of contributors -"do we like it"). It is my personal preference, so if we don't like it - please COMMENT. I don't want to force-push any personal preferences.
Reformatted all files to new style.
Specified clang-format version for pre-commit check.
