Tdesktop: Use system window border/frame/header

[mekras]

After last update on Linux Telegram started to use own window border instead of system one. This is an UX degradation because prevents users from using the management mechanisms provided by desktop/window managers, such as custom buttons, effects and etc.

There should be an option to use a system border on Linux.

This is not a duplicate of #2958 at all. Up until this last update, Telegram Desktop on Linux has always used the native decoration, but now its using the native one, with no option to change it.

Use system window border/frame/header

Set native windows frame

100% duplicate

Up until this last update

This doesn't make this issue a non-duplicate, since it is the same decorations, just cross-platform due to the new Qt APIs now

Please rollback that change. I want and I like my native KDE window decoration. Right now It's awful.
Or make this OPTIONAL, let the users to choose which one to use.

"committed 22 hours ago" really? haha.
Updated to v2.1.18, now I can switch back to my beautiful native KDE window decorations. Thx.
