Draft: Issue #3442423 by agamich: Re-write gulp file and update gulp tasks
Within this Merge Request was updating gulpfile, gulp packages, and gulp tasks.
After updating gulp scripts
and gulp scripts
tasks should re-compile all style/script files,
because browselist(for styles), babel(for scripts) and some packages were update.
Also here was added .bablrc, .editorconfig, .eslintrc.json/.eslintignore, .nvmrc files.
