Version 2.4.1

Improvements to rails 5.2 patches

Monkeypatch activerecord relations to work with rails >=5.2.0rc2

Test new ruby versions

Add a very soft deprecation notice

This isn't a change from how paranoia has been developed for the past
few years, but makes it more explicit.

I hope the recommendation against new projects using paranoia isn't too
controversial. I think anyone who has used this gem extensively has been
surprised by it many times. This is just the nature of replacing
ActiveRecord's behaviour. I believe paranoia does extremely well given
that it does that.

A lot of developers will reach for paranoia or acts_as_paranoid because
they're the first result they will find. However most users are just
looking to hide or disable some records, and they would do much better
to just toggle a flag rather than have paranoia override ActiveRecord's
behaviour on their model.

I hope linking to discard here isn't inappropriate, I believe it's the
best resource describe the caveats of paranoia as well as give a good
example of how to soft-delete without needing paranoia or
acts_as_paranoid.

Test with Rails 5.2

Version 2.4.0

Add paranoia_destroy and paranoia_delete aliases

Version-related cleanup

Rebase of #412

This removes the assumption from `really_destroy!` that there is
only one column value, the deletion date, that needs to be updated
on a model that is being `really_destroy!`ed. Instead, use the
defined `paranoia_destroy_attributes` as they are used in `destroy`
and other calls.

This prevents an issue where the DBMS will complain when trying to
`really_destroy!` one of these models, given that paranoia is
attempting to insert a DateTime value into a boolean (or otherly-
typed) column.

Fixes #326

This makes paranoia's code itself more explicit.

This should help users be more explicit about what action they want to
perform. My hope is that this will also make it easier to migrate off of
paranoia.

Update .travis.yml

Removed the pessimistic dependency requirements.
Updated Ruby versions.
