Fixed some typos and grammar in the README file

fix for showDropDown method

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

There was a type in the boolean reference to save_local

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
