ServerListPlus 1.2.0

Thanks to @FllipEis for multi-select, tab reordering and the
sidebar rework (#1).

Added

• When a newer release is on Modrinth for your Minecraft version and loader, the game log says so
  and an update icon appears next to the settings in the server list. It can be hidden until the
  next version, and the check can be turned off in the settings.
• Several servers can be selected with Shift + click (a range) and Ctrl/Cmd + click (one more or
  one less), then dragged together, dropped onto a tab, or put into folders, pinned and hidden
  from their right-click menu.
• Tabs can be reordered by dragging them, in the row and in the sidebar.
• Option to auto-hide the sidebar: it slides in while the pointer is over its place.
• A dragged server is shown as its whole row instead of only its name.

Changed

• With the sidebar, the server list keeps its full width, so the rows stay centered under the
  title, and the search field and settings sit at the top of the sidebar instead of above the list.
• The tabs in the row are centered over the server list instead of the space left of the icons.
• Sorting moved into the settings menu; the settings icon is highlighted while a sort order is active.
• The sidebar's "+" became a "New folder" row.

Fixed

• Server icons flickered to the default icon when switching tabs.
