Small error in the wiki

[dddotsev]

Hello,

I found a small error in the wiki: https://github.com/marceljuenemann/angular-drag-and-drop-lists/wiki/Data-Transfer-Design#workaround-for-micorsoft-internet-explorer

In that paragraph there is a list, in the second item in the list it says that the data transfer object looks like {item: ..., mimeType: ...}, while it actually is {item: ..., type: ...}, as set here: https://github.com/marceljuenemann/angular-drag-and-drop-lists/blob/master/angular-drag-and-drop-lists.js#L117

It's a small thing, but it took me some debugging to see what's the issue, so I just created the issue so it could be updated.
