Clicking while holding shift now selects a ThumbCell and allows the
multiple ThumbCells at one. The actions in the context menu are applied
to all selected models. "copy url" is disabled, if multiple models are
selected, because that doesn't make sense.
Add combobox on the bottom of ThumbOverviewTab.
Add integer thumbWidth to the Settings to save and restore the selected
value between sessions. Set the selected value for all thumbnails on
all tabs.
If the display of stream resolution is enabled in the settings, the filtering now takes the resolution into account.
So you can filter for "1080" and only get streams with a resolution of 1080p.
