Expands on @Hermanverschooten's suggestion in #695, adds a way to disable PT in all threads, hopefully fixes #635.
Initially, I was concerned about having both a thread-safe flag and thread-unsafe flag. This PR mitigates that concern by giving these methods very explicit names, like
enabled_in_all_threads=
andenabled_in_current_thread=
.config.paper_trail.enabled
. See initializer inpaper_trail/frameworks/rails/engine.rb
Ben, I liked your suggestion in #635 that the all-threads flag be immutable, but I didn't see immediately how to implement said immutability given the way we apply the rails config option in
engine.rb
.
