Add new CSS framework to the tutorials page

Remove some unused code from the neocities index file and default template index file

Killed lots of white space in the files i touched...
typo. more white space.

typo on abut.erb

more whitespace conversion. (sublime just does it automatically)
CSS update for small screens

fixes a padding-left issue where the file list was bumping up against the left edge of the browser window on small screen sizes.

Also swapped out style="float: right" for the class "float-Right" on the right column menu icons.
