#848 ability to add alternate extensions (.zipped, .zap)

[Anonymous]

7z is a lovely program but what would make it even better would be support for adding your own file extensions (with shell support)

The reason for this is that since some email services started blocking emails with .zip extension, people have stated renaming .zip to .zap or .zipped or all sorts of other things. It would be nice to get inbuilt support for this
