Minor site changes

Updated the design of the top navigation links, removed the old "share" link for twitter and facebook, and replaced it with a smaller module that also includes the ability to share with email, twitter, facebook and G+. Also the new module will allow you to share a post from the main page. With the previous module you had to be on the post's page to share that particular post. Hopefully these minor changes will make navigation easier, more streamlined, and less obstructed. More minor changes will be coming in the next few days/weeks, as well as a complete rebuild of the store, which is a fairly new feature of the site. I also brought back the link for the "helpful phone numbers" page. The page never left the site, I just had removed the link to it a while ago, but it is now back. Feel free to leave comments here if you think that there are other numbers that should be included.
