Add Item ID to "continue shopping" links on site/search results. fix java issue.

[tomcat8118]

site.

http://www.contractor-licensing.com/component/com_virtuemart/Itemid,100013/categorylayout,0/view,category/virtuemart_category_id,0/

joomla 2.5.17, vmart 2.0.26

when adding an item to the cart, you are then prompted to continue shopping or checkout. 

when you click continue shopping, you will lose the menu item id, thus resulting in key modules disappearing.   same thing happens when searching.

i have a show cart module on the top right corner.  when viewing the cart, i would like for the modules to disappear.  however, when clicking continue shopping, you should be taken to the bookstore main page.

some java is not working right/template elements.

i will request a full change log for future updates.
