Sweetalert Versions Save

Changelog:

• You can now install SweetAlert through NPM. Just run npm install sweetalert to get started!
• AMD & CommonJS support! You can now avoid running SweetAlert as a global function if you want to. Thanks @danreeves and everyone else who has suggested this enhancement!
• Ability to hide "OK/Confirm"-button with showConfirmButton: false. This can be used if you prefer using a timer, or in combination with allowOutsideClick.
• Removal of generic class names (such as .confirm, .success... etc). All classes are now prefixed with .sa- to remove potential conflicts with your own stylesheets. Thanks @sushantdhiman!

• Add IE8 and IE9 support.
• Update README with browser compatibility info
• Initialize DOM elements on first usage instead of on page load (Thanks @peterjosling!)
• [BUGFIX] Fix custom image size attribute
