About dialog: add a link to the current commit

![](http://i.imgur.com/EAkl6Gh.png)
Seems to work fine without? The [code example in the docs](http://msdn.microsoft.com/en-us/library/system.windows.forms.linklabel(v=vs.110).aspx) doesn't have it either:

```cs
this.linkLabel1.Links.Add(24, 9, "www.microsoft.com");
this.linkLabel1.Links.Add(42, 3, "www.msn.com");
```
