Error on `Cargo.toml` file generated

[Rivee]

Hello,

it's been a while since I want to install this window manager, I follow the tutorial but once I create my config file, I can't generate the dynamic library needed by the program.

This is the error I got when I type cargo build

    Updating git repository `https://github.com/Kintaro/wtftw.git`

@Rivee seems like Cargo.toml is broken in wtftw-contrib, here is a fix.
