[Keyboard-Manager] Warn on remapping internal PT-shortcuts

[htcfreek]

I thought about if we could warn the users if they remapping keyboard shortcuts used in other PowerToys.

Detailed description

We have many keyboard shortcuts in all the PowerToys and the user may not know them all.
So if the user remap keys used in other PowerToys the regarding PowerToys don't work as expected.

Can we warn the user in that situation with a warning message like this: "Attention you remapping a shortcuts used in PT_USING_THE_SHORTCUT! This could lead to an unexpected behavior."?

depends but most apps are unaware of one another. no way for PT to know another app remapped something
