Changes to speed up website part 2
This is a new pull request because I couldn't figure out git. I am sorry about the confusion.
I have gotten rid of the stylesheet from fontdeck since fontdeck has shutdown. Doing so should make the site load faster. I also upgraded jquery to the most recent version. Javascript is defered which means the javascript executes once the page has been parsed.
I changed the color of links to a blue to make the site more color blind accessible. The footer text is now black so the text is easier to see. HTML lang attribute is set to English.
I updated the _config.yml file to use plugins instead of gems. I got a warning that gems is deprecated and plugins is current way to load gems.
