Added about page.
Added js function to calculate age.

I may use it in the future.
Externalized/reused code for side navbar.
Changed address to Bootstrap doc 2.3.2 site.

This is because the old address started to not refer anymore to
the site from which I based the site. This happened because of
Bootstrap 3 release.
Deleted all the previous junky lines.

The comment in file left by the bootstrap docs authors made it
clear that I all js in this file was junk.

I just didn't delete the function to calculate age that I had
previously added to this file.
Corrected typo: takinng -> taking
Added new page called contact.

I also added some jquery to the applications.js to handle the
exposition of my email in the contacts page.

I also deleted two links from the top navbar and added one link to
contacts. I deleted the link to apps and more.
Updated the about page and reused an about text.

The text reused was put in a partial and it is used in the about
page and in the home page.
Small modification in the text.
Added local_resources folder to .gitignore
Changed Gemfile
Inserted last paragraph of about into a div.
Deleted .html from urls in the top_navbar.
Deleted .html from url that points to curriculum.
