Portfolio: details popup window

[zainsadaqat]

In this pull request, I implemented the following features in my portfolio:

• In order to associate each project with the popup window details, I used a JavaScript array to store all of the information for all projects.
• For each project, I stored the following pieces of data in a JavaScript object, name, description, featured image, technologies, link to live version, link to the source.
• I updated the main page so that the projects section is created dynamically using the information stored in that JavaScript object. All the HTML in that section is created when the page loads.
• After that, I implemented the popup window.
