Fixed some problems and added favicon.

Added a favicon and fixed the following problems:
<ul>
<li>Resources per 5 seconds display updated every 5 seconds, rather than when the value was changed.</li>
<li>Pressing buttons visually kept them in the pressed state.</li>
<li>The information and research box cut through the last entry. </li>
<li>Content size did not match the window size (scroll bar would always appear along the bottom of the webpage).</li>
</ul>
