Add button that leads to search for other QSOs with the same DX station

[phl0]

Thought this could be useful (saves me from copying the callsign to the search box). With a click on the button you will be directed to a search for QSOs with the same DX station.

Tested working ok.

Though while testing, I did find that search acts strange when the call has a / in it. It searches for everything that contains what is in front of the slash in the call. I don't know if this is intentional, or a bug.

Tnx for testing. I can confirm the issue with slashes in the callsign though it is not caused by this patch as far as I can see. Will see if I can find a solution.

Strange. I cannot reproduce this... Does it only happen to calls with prefix and suffix?!

[AndreasK79]

It seems to happen with prefix. It was with the call LA/SP7VC where I noticed this behavior.

[AndreasK79]

I'll make a separate issue on this.

[phl0]

Oh right. QSL on the issue with prefixed callsigns. As such not an issue of this PR. So got for merge here imho.

[AndreasK79]

As mentioned above, it has nothing to do with this PR. I should have made a separate issue when I found it.
Go for merge :)
