Creating the veryColorful Theme

Starting from the _s template generated at underscores.me (using the name pinkIt) I made the following modifications to get the theme the way I wanted it:

functions.php:

Added support for a 2nd sidebar
Added support for all available post-types

header.php:

Removed the navigation bar

sidebar.php:

Added the dynamic navigation bar as the first module on the left sidebar (before the dynamic widget area)
Added the 2nd sidebar (#tertiary)

style.css:

Added a background image in the body section
Added layout styling for sidebar-content-sidebar copied from the layouts folder (included with the generated theme)
Changed the font color to white
Changed a:visited to cyan
