Fixes for s3 api, Added events, Bootstrap3 progressbar, extra headers

[dotansimha]

Changes:

• Fixes for s3 API (changed the "key" to "AWSAccessKeyId")
• Change progressbar template to work with Bootstrap 3
• Added events for start upload, upload done, upload failed
• Added ability to add custom headers for upload request.
• Changed HTTPS to HTTP to support non-https sites

Usage example:

      $scope.s3UploadOptions =
      {
          getOptionsUri: s3ErasOptionsUri,
          folder: "",
          acl: "private",
          uploadStartCallback: function()
          {
          },
          uploadDoneCallback: function(fileUrl, fileKey)
          {
          },
          uploadErrorCallback: function()
          {
          }
      };

Hi there,
few questions:

1. Why did you change the url to http instead of https ? It shouldn't be a problem to access secured resources from an unsecured resource, but it doesn't work the other way around.
2. Why did you change "key" name ? I'd rather leave it as is to keep backward compatibility
3. I just merged another pull request that added custom events to the upload service, would you mind look at it and let me know if it suits your need ?

Hi,

1. actualy changed it because of some problems I have specific in my enviroment that related to the https... I can be reversed to https.
2. I changed the key becuase the current API required that the name of the property will by AWSAccessKeyId... I dont think that backward compatibility is required as the "key" is not a valid property in S3 right now...
3. It actually suits my needs and looks good.

Also, accessing from HTTP to HTTPS might cause some errors related to Cross Origin.
I think it should be a configuration option..

Hi Dotan,
Do you mind updating your code following our discussing here ?
I mean remove the code duplications and adjust to the latest version of s3Upload ?

I'll be more than happy to merge your pull request afterwards.
