v2.1.0

• Enhancement: Switched multi-select type from Library to Gallery. You no longer have to hold the SHIFT or CONTROL/COMMAND keys to select multiple items. To restore the old behavior, use the new fg_use_legacy_selection filter. See docs for details.
• Bugfix: Fix broken details sidebar hiding filter. The details sidebar is now properly hidden again by default, and can be shown be using the fg_show_sidebar filter.
• Under the Hood: Complete rewrite of all CSS styles. FG styles are now isolated and don't affect other media manager modals.
