filter: add filter preset table

Add a table view that shows all presets and a button to delete
old presets. When clicking on an item, load the preset.
When the filter is reset, deselect any item.

Change the preset-loading code: instead of simply loading the
preset, select the preset in the table. Thus, it will be loaded
implicitly.
