Adding scrollbar to projectlist in index.html

[Olibad]

This pull request adds a scrollbar to the project list when the list is too long. The height of the project list is dynamic to adjust to the user screen.

I am new here, so forgive me if I ask an ignorant question. I downloaded it on Nov. 3, 2017, and the problem with the project list remains. Has the master (via the download button) been updated?

I played with the css for about an hour today. While adding the scrollbar to a given object is trivial, finding the proper element in the css files proved daunting. It might be useful to accept the change proposed by Olibad and add an issue to review and revise the css at a later date.

I took another shot at adding scroll bar to the project list. It appears to work as desired by adding two elements, overflow-y and height, to boostrap.css selectors "ul, ol" at line 587.

ul, ol { margin-top: 0; margin-bottom: 10px; overflow-y: auto; height: 500px; }
