html viewer

Allows editing file with format.html. With this editing process, we can allow fixing each line and each component and then saved with the HTML file format after being edited.

Actually, this was planned already, since I have created the xml viewer and was really helpful at least to me, I was planning to also add an html parser and editor one day.
