HTML To RTF

This project convert html to rtf format in the browser. It is based on the oziresrds/html-to-rtf awesome project. I looked into the 20+ forks to try get the best parts glued to in one place. This could be called html-to-rtf-frankenstein lol.

Highlight for the developers:

• Ozires for the base framework. Without him, we would not have this.
• Heron Silva for several improvements (as font-family support) (heronsilva / html-to-rtf)
• wodka for making it possible to use in browser (wodka/html-to-rtf).
• Leon Strauß for image support (MinePlay96/html-to-rtf).

If I missed some functionality in other forks, please let me know, or make a PR.
