Add other new slick methods

2.1.1

Update directive to 2.1.0

Updates to slick 1.4.1

No changes to the directive functionality itself.

Just an FYI on all the slick methods exposed by the directive on the scoped slick variable: Its no longer necessary. Slick exposes methods directly in $.fn.slick(<methodName>, ...) manner.

Add uglifyjs for minification

• Now supports custom url with src attribute. No more no-tpls.js needed.

• Eradicated need for timeout in directive link function
• Shows video examples
• Provides hooks for image and video mimeType validations
