itch install fails with: No manager for installer unknown

[rcorre]

When I try to install the ToF Linux 64 v0.7 build from the itch.io app on ArchLinux, the installation fails with: No manager for installer unknown

This could be an itch issue (and I did send a report to itch), but given I've installed other games successfully I thought I should report it here:

I'm not very familiar with itch.io app, though I used it to install ToF long ago and it worked. ToF does not require installation, it should just download a file and set permissions.

I think the itch app might be confused by the .bin file extension and not know how to handle it. The log even suggests it did download the file, but has no "mapping" for bin file.
