add setting to include self-updating casks (--greedy), on by default

brew outdated normally skips casks that auto-update themselves; with
includeGreedyCasks enabled (the default) BrewBar passes --greedy so they
show up too. Toggling the checkbox refetches immediately since the list
semantics change.
