Adding, improving, and editing header, grid system, and interactivity

1. Changed header from image to text/type as per feedback.

2. Added jQuery fittext functionality that resizes text for adaptive
design.

3. Changed and updated font families.

4. Added grid system developed by jQuery + CSS, adjusting code for own
usage. (such as removing unnecessary animations, adaptive window resize
measurements, border adjustments, padding/margins, debugging by adding
callback function to jQuery code, etc.)

5. Added jQuery and css for hover effect for project images: tinted
background and pop-up commentary (project title and description).
Adjusted jQuery function by removing unnecessary code.

6. Added a favicon for fun!!
