Configurable interactive resize modifier

[notpeelz]

Would it be possible to make the mouse resize modifier configurable?
I have my caps lock mapped to Mod5 via my xkb config, and I use mod5 for all my shortcuts. It would feel more natural if I could also bind the mouse resize modifier to Mod5.

It's not configurable at the moment, it's equal to Mod. But it shouldn't be hard to edit in the code, in input.rs mouse button event
