Spreadsheet view filter: make it configurable or search in all visible columns

Description

Tying "filter" results only for reference designator column (as currently is) makes filtering functionality almost useless:

1. 
2. 

Filter should search inside all visible columns, or user should be able to point to which column filter should work with.

Steps to reproduce

1. Try to filter out components with package 2917 (exist inside "Value" field) or 7343 (exists in "Footprint" field) by entering inside "Filter" textbox;
2. Get zero results for text entries of "2917" or "7343";
