[vQmod] Remove category product count

1) This vqmod will remove the backend queries that make OpenCart slower when there are many categories/products.
2) You can remove frontend category count display from admin, System > Settings > Edit > Option > Category Product Count and set it to 'No' ;

- This mod removes queries from header controller and category module controller
- Most modules only remove the category count from frontend, but all queries still take place !!
- This is the module that you need, the difference is noticeable.

TROUBLESHOOTING
==================================
- This module has only been tested with OpenCart 1.5.4.1 and OpenCart 1.5.5.1.
- It might not work with previous versions of OpenCart, if so, you can delete it. It only virtually modifies OpenCart files, so no need to worry.
