Add comprehensive download and setup instructions for Java Homework project

[Copilot]

This PR addresses the common question "how do I download this" by adding detailed documentation for the Java Homework Map Editor project.

What's Added

Enhanced README Documentation

• Multiple download options: Git clone and ZIP download with step-by-step instructions
• Platform-specific run commands: Separate instructions for Linux/macOS (run.bash) and Windows (run.bat)
• Prerequisites section: Clear requirements including Java JDK 8+ and GUI support
• Troubleshooting guide: Common issues like missing Java, headless environments, and compilation warnings

Project Structure Explanation

• Detailed description of the MVC architecture files
• Explanation of JSON save/load functionality
• Overview of animated features (strafing statues, growing mushrooms, jumping turtles)

Repository Improvements

• Added .gitignore to prevent compiled .class files from being committed
• Enhanced main repository README with quick start section
• Removed accidentally committed build artifacts

Example Usage

Users can now easily get started with:

# Clone and run on Linux/macOS
git clone https://github.com/ceddy1274/Homework.git
cd "Homework/Programming Paradigms/Java Homework"
chmod +x run.bash && ./run.bash

Or on Windows:

run.bat

The documentation makes it clear that this is a GUI-based Map Editor application that requires Java and a graphical environment to run properly.
