[Lazarus] New Lazarus package - MouseAndKeyInput

[Felipe Monteiro de Carvalho]

I think it would be cool to explain where it is located (I suppose
lazarus/components/mouseandkeyinput ) and in which widgetsets it is
implemented. Even better a grid like in the Roadmap wiki page about
which features work in each widgetset.

I didn't look at the code, but SetMousePos doesn't need
reimplementation on each widgetset as it's already implemented in LCL.
Just a hint

thanks,
