Foundry VTT Version 11 Support

[WesWedding]

Is your feature request related to a problem? Please describe.
The module is not usable in Version 11 of Foundry VTT.

Describe the solution you'd like
Version 11 support.

Describe alternatives you've considered
I simply updated the supported versions in the manifest and it seemed like the module still worked pretty good! I am not very experienced with Foundry nor this module, though, so my word should be taken with a grain of salt. I'm trying to use a module that depends on this one.

This is partially done and you can install on foundry 11, but the configuration menu styling is messed up and the secret disposition isn't handled.

Also, if you installed the fork that @akselander made, you'll need to uninstall and reinstall because the manifest included in that release is malformed and breaks the foundry updater.

Thanks for fixing, I deliberately disconnected my fork from this one, but perhaps I could have named it differently so it's more clear.
