[feature request] nemo seahorse: default extension configuration

[karrakoliko]

When encrypt file using nemo seahorse extension, default output file extension becomes pgp.

This seems not be configurable at all: used extension is hardcoded.

I'd like to use gpg by default, and in order to do that my only option rn is to patch and rebuild whole extension.

Could you add configuration (like ~/.config/nemo/extension/seahorse.conf with encrypted_file_extension = "*pgp/gpg here*"?
