[Media] Qt Bridge 0.4 and Technology Preview

Hi everyone!

Yesterday we released version 0.4 of the qtbridge crate. The technical changes to 0.3 are relatively small. We focused on local hardening and bugfixes and exchanged the QMethodInvoker with a type safe QThreadHandle.

More importantly, we took the next step and entered Technology Preview. It is an important step for us, showing that we get closer to the first stable release. The core API is mostly in place but might still change in a couple of places. That also means that your feedback is now more valuable than ever.

Thanks to everybody that gives this a try and gives us feedback. We already got quite some good input that we are very grateful for!
