1.0.0-beta.7

Project Changes:

• Switched from Webpack to Rollup.js for better bundle sizes and cleaner bundle style.
• Refactored the src/directive.js file to be a lot cleaner, there is a seperate module that handles attaching listeners in src/listeners.js.

General Changes:

• Some polyfills are not longer included in the build for better sizes, typically you already use polyfills in your projects.
• Added support for radio inputs validation mentioned here #20 checkboxes still pending.

Fixes:

• Fixed an issue where triggering validation for a specific scope would have a side effect on other scopes.
• Fixed an issue where vee-validate would fail in IE because of Object.assign and provided a basic polyfill.
