[Icon changes] Symbolic on KDE System Settings and other things

[buufmax]

Many thanks for fixing so fast issues at #197.

I am coming up again with some more requests to replace symbolic icons in KDE Plasma 6 - System Settings with regular colors icons.

• System Settings > Colors & Themes Night Light & System Sounds

• System Settings Screen Locking

• System Settings Spell Check

• System Settings Auto Start

That's it for the symolic icons on the main System Settings, if you can replace it with standard colored icons i think it would be more appropriate. Something else in System Settings > About this System.

I use openSUSE Tumbleweed, and the main logo here appears with Ubuntu icon due to distributor-logo.svg is linked to distributor-logo-ubuntu. I think that "distributor-logo" must not have a specific distributor icon ie Ubuntu, but something general to represent each systems ie : Tux icon, Linux icon, Info icon and so on...

And one last request,

• Status and Notification KTorrent KTorrent icon on tray must have a symbolic icon.

• Status and Notification Disks & Devices This icon is too thickened, if it could be a little thinner like other recent refreshed on tray?

I hope you will consider those in future updates, thank you for this fantastic package that made KDE enjoyable to use.

Most of the above requests have been fixed periodically according to different requests.

Closing!
