2nd Devlog - more window functions, improved code efficiency

• Made classes and functions to organize code and improve efficiency (hadn’t bothered earlier because I wasn’t familiar with javascript enough yet)
• Implemented a second window with the same functionality as the welcome screen (opening/closing, dragging, moving to top when clickeda) and prevented users from dragging windows into the top bar. Hopefully, I’ll make this app into a text editor.

By next devlog, I want to also add window resizing and borders for the other edges of the screen.
