Feature Request: Add custom command for gestures

[moltencrux]

It would be really great if you could add the ability to execute a custom commands so that users could invoke scripts upon mouse gestures.

A variant of this would be to let the user define custom gesture-to-key mappings. That would massively increase the interoperability with e.g. the Tiling Shell extension.

I've changed the mapped keys for tiling on my machine with this commit.
