build(package.json): Add support for "commitizen" and "husky"
build(package.json): Add support for "commitizen" and "husky"

Had added everything for "commitizen" package some time back (except itself **face palm**). Added
"husky" package, which provides Git pre-hooks, allowing *forced* test prior to commit. Changed
"yargs" option to its actual value. Bumped package version (which should have been done a while
back).
