Cart Start

I have enabled the hikashop cart module and have positioned it in the
header.
Working shopping cart

This is a basic working shopping cart with no jQuery and little CSS it
is just the cart in a working state nothing more.

Had to add some jQuery to get the items number and the button is also
not hikashop it will be used to show the full cart.
Ajax based Shopping cart

I have developed the cart with jQuery so that there is no page load when
a item is deleted, when the last item is deleted it will update the html
with new contents
sorted CSS for shopping cart

I lost the CSS for the shopping cart so I have gone back to old branch
and manually copied the CSS and transferred it to this commit
