[0.18.43] Loud error sound on successful blueprint import

[Xorimuth]

To reproduce:

- Copy a valid blueprint string from eg factorioprints.com
- Click 'Import string' ingame
- Paste string in
- The text 'Blueprint imported successfully' appears and the blueprint is successfully imported, but an 'error' sound plays as well

Maybe this is the intended sound? It sounds wrong to me though.

Hello, I agree. We will put some kind of success sound there, I removed the sound on success for now, to at least avoid confusion (it also confused me when I was using it).
