Breaking change in 4.0.0

SweetAlert2 now rejects Promise reject(dismiss) in cases:

• Cancel button was clicked (dismiss will be "cancel")
• Overlay click ("overlay")
• Esc press ("esc")
• Timer ("timer")

Before 4.0.0 Promise handling:

swal({title: 'Are you sure?', showCancelButton: true}).then(
  function(isConfirm) {
    if (isConfirm === true) {
      // handle Confirm button click
    } else if (isConfirm === false) {
      // handle Cancel button click
    } else {
      // Esc, close button or outside click, isConfirm is undefined
    }
  }
);

Starting with v4.0.0 Promise will be resolved in case of Confirm button was clicked and rejected with dismiss parameter on all other cases:

swal({title: 'Are you sure?', showCancelButton: true}).then(
  function(result) {
    // handle Confirm button click
    // result is an optional parameter, needed for modals with input
  }, function(dismiss) {
    // dismiss can be 'cancel', 'overlay', 'esc' or 'timer'
  }
);

Add Promise support for input-radio and input-select

Add input type file

Add showLoaderOnConfirm parameter

Add resetDefaults() to chaining modals example

Add queue() method for chaining modals.

• add resetDefaults() method
• switch to stefanpenner/es6-promise
• add NPM postinstall script to ignore changes in dist by default
• change main JS file in bower.json

• small fix for use 3rd party animations.
• remove not used param lastFocusedButton.

Fixed https://github.com/limonte/sweetalert2/issues/151

Helper functions and some static data are moved out of the main source file and into their own respective utils/*.js files. This kind of approach will help in the long run as more features are added, the main scope isn't going to be completely bloated.

The main lengthy block of code that sets the users provided options is replaced it with the extend() helper.

Removed module specific code from the source and added it to a package wrapper instead. This allows exporting for many different bundler types, and clean logic.

• reimplemented production minification
• explicitly listing module files for npm

If window is detected it will automatically extend it with sweetAlert and swal
