Initial focus is set on text entry component

[hinerm]

When launching Fiji with Jaunch, focus is initially set on the search bar.

With fiji-windows-x64.exe:

With ImageJ-win64.exe

This is a minor annoyance but a change in behavior, and will surprise people who are used to opening things with shortcuts after starting Fiji.

I tracked down the problem to the inclusion of the -Dimagej.splash=true flag. As a workaround, you can comment out this flag from your fiji.toml. We will need to dig into the net.imagej.launcher.SplashScreen class in imagej-launcher in order to fix this properly.
