Add support for Client Side Tokens (#245)

* add .idea folder to .gitignore, used by PhpStorm and other Jetbrain IDEs.

* Add ability to provide client_side_token instead of seller_id, the client side token will take precedence over the seller id, as you cannot specify both.

* Update .gitignore

* Update js.blade.php
