Fixed a few warnings #1870

Closed HeCorr closed 2 months ago

HeCorr commented 2 months ago

This PR fixes a handful of simple warnings, mostly missing emit keywords and unused QStrings.

There were a lot more warnings but unfortunately my Qt and C++ knowledge isn't good enough to handle those so I decided not to risk breaking something. At least I fixed more than just the missing emits.
