Added Social Comments (read details)

1. Fixed how index is displayed in A1/index.html . For some reason it
was referencing all .js and .cs files as if they were in the same A1
folder. So I changed “./“ to “../“
2. Added “htmlcommentbox” module to A1/index.html
Usage: click on a grey border at the bottom to start. click on same
grey border to stop comments.
