Support for master filter list #72
Description
Instead of having multiple filter lists, idea is to have all filters collected in master list and then you can save/load VIEWS to that same list with different filters enabled. When you add a new filter it will be added to master list and is therefore visible in all views so you don't have to manually add the same filter to all saved filter-configurations. Filters added via one view should be disabled in other views by default.
Also default view option should be added so that whenever you open a file, default filters are applied.
