Assembly listing text hard to see with dark themes

[ctrlaltmilk]

What's wrong, and with what software version?

Operating System: Arch Linux 5.14.7
CEmu version: v2.0dev (git: 0f45ce7)
Describe your issue:
Using any theme with a white foreground and dark background means it's incredibly hard to see any white text on the currently selected line.

What are the steps to reproduce this issue?

1. Open the disassembly view using any theme with white text on a dark background, such as KDE Breeze Dark.

Any logs, error output, screenshot, other comments...?

Yeah, not actually OS-specific, it's just that color choices aren't indeed always good in dark mode. I've tweaked a few already as I encountered the same issue on macOS before, but I need to finish the work I guess.
