Backend filters

[sandomatyas]

If you use a filter on the backend and do something with the item the filters lose their values.
Test scenario:

• open VirtueMart -> Products
• Search for a product name
• publish/unpublish it

Also it would be great to use another filters, too. E.g. published status, parent or child, etc
Tested with Joomla 3.4.5 & VirtueMart 3.0.11
