* Add a dedicated version option to CLI11 to facilitate use of version flags, similar to help flags * add some test for the version flag * update errors and formatting * clear up gcc 4.8 warnings * add a few more tests * fix compiler error * fix a few comments, and change default version flag to only use "--version" * remove `version` calls and tests * formatting and add `std::string version()` back in.
