suggestion: replace currently linked sketch file

[Christian-Peter]

Hi guys,

first I want to give praise to the author of the currently linked Sketch file to having contributed his work here.
When using it If found it's scope quite limited though and was lucky to find a link to a sketch file (and Adobe Illustrator) which actually includes many more (if not all) semantic-ui elements.

The one I found is located here: https://github.com/garystover/Semantic-UI-Kit by Gary Stover

Please note: I am not a creative commons person so those in the know please give it a look that the current license is what we can use here.

Let me know your thoughts.

Christian
