Modernized Exceptions Lectures, TWP54_2 & TWP54_3 (both english & spanish). The lesson previously was written in Tkinter GUI for desktop apps, looking outdated and requiring a PC to execute it. So this PR rewrites the code for the web (HTML5) and make the lesson interactive in the browser using Brython Event Handlers. Partially completes #217
