There are HTML and Re:VIEW Processor plugins for textlint. We should support them.

Currently we have only one customizable ruleset, but it is great to allow user to create multiple rulesets. Pre-defined rulesets like English, Japanese and Japanese Novels should also be edittable.

Because textlint-rule-prh uses local YAML files as configuration, we need special treatment like allowing user to write YAML file in options view.
