Added @products and @categories table groups for database dumps

@paales GIST here gets the credit: https://gist.github.com/paales/8229883 but I think this should be a core feature for database dumps :)

Thank for this. What's up with bundle tables?
I'm not sure if the table list is really complete.

I have based it loosely on https://gist.github.com/philwinkle/0a1725635204e07a69a5

What's up with bundle tables?

Not sure if I understand what you mean, all bundle tables are excluded as far as I can see.

[cmuench]

Yes, that's the point. Product data is much more. If you use i.e. the @sales group you don't wanne have any data of orders. If i add @Product i don't wanne have any product. If a bundle product exists we should exclude the bundle data also.
Before we merge this we should check if the table list is really complete for all standard product types.

Suggestions:

• downloadable_
• product_alert
• rating?
• review?
• tag
• wishlist

Bonus Questions: How does it handle url rewrites if the products aren't available? I believe the URL rewrites have a foreign key to the product.

I close this pull request. The task is much more complex. We need another solution to support this.
