FLIP hotkey F not work with PIPEs/BELTs/CONVEYORs like with BUILDINGs

Issue description

Flip hotkey behavior not consistent.

Reproduction steps

1. Place any building.
2. Place any pipe/belt/conveyor not connected to anything.
3. Move mouse cursor over building and press hotkey F --> flip building.
4. Move mouse cursor over pipe/belt/conveyor and press hotkey F --> does nothing. Why not flip direction? By logic it's must work.

It's very annoying to click on every pipe/belt/conveyor part to flip direction.

Game version and build number

v0.6.3

Operating system

Windows

👍 this is a really good idea.
letting 'F' button flip the pipe/belt is a logical and intuitive solution.

Same issue for game version v0.7.8
