Reorganized the menus so that each property-panel first has a simple list of present quantities followed by a more detailed section for properties that have more options.
Added search filter for polarized/non-polarized DOS and band structure.
Added method type filter for energy-volume curves.
The EELS search criteria are now shown in two different locations: method/eels and properties/spectroscopy/eels. If we can make a clear distinction between properties/method (e.g. is resolution set by the method, or is it determined from the result?) for EELS, we could modify the shown filters.
Updated the look of FilterSummary that contains the chips for each present filter: now the targeted metainfo name is always shown above the chips. This makes it easier to see which metainfo is targeted and also makes the nested and non-nested filters look exactly the same.
Added support for requesting aggregations for boolean fields (needed to show statistics for boolean search filters).
Fixed issue with InputSlider not being full-width.
