Added pulldowns for query and filter. Added filter notifications, moved timepicker to navbar, reimplemented auto refresh

Refactored drag/drop, moved header buttons around, disable drag on panels inside column panel, updated default panels with panel titles

Bettermap Group Colors

Better-looking histogram checkboxes

switched up the build process a bit more, so most of the build occurs in-place, meaning the src and dest options are the same. This allows us to simple copy everthing at once and not need to specify all the edge cases like I did previously in copy:everything_left_in_src

fix the path to the leaflet image directory

Make panel extra icons more obvious, fix overlap, add tooltips, add method for panels to define custom modals
