v1.0.2

This release fixes a bug where some files that are not HTML files but also aren’t treated by Jekyll as static assets—for example, XML feeds and sitemaps—could have HTML header erroneously prepended due to this plugin, causing them to become malformed in rendered site. Thanks to @Rp70 (as well as @cargocultprogramming, @axb21).

Note: as of this version, only files with .html extension will be processed by the plugin.

It also pins Nokogiri version to match 1.x.
