Worked great for free plugins

For some reason, the Sucuri function that does this, would not work, especially on localhost. This plugin did the trick for free/repo-based plugins.

I tested it by placing random comments in plugin files, and random files in the plugin’s folder(s), and the force re-install removed all of it. This means that it overwrites the entire plugin, and does not just replace files one-by-one. Nice. Use this in bulk mode, to get the normal WP Dashboard feedback.
