Clippings for Thunderbird 6.0 release candidate 1

What's New:
• Compatible with Thunderbird 78
• The Clippings Manager window and the New Clipping dialog have a similar look and feel as the same found in Clippings for Firefox
• It's now possible to drag and drop clippings and folders in the clippings tree list in Clippings Manager. This feature has been broken since Clippings for Thunderbird 5.6, and is finally fixed in version 6.0
• In the New Clipping dialog, you can now preview the clipping when applying the options to create as unquoted text or remove extra line breaks
• Available in Dutch and Portuguese (Brazil)

Things You Should Know About:
• Clippings for Thunderbird 6.0 is compatible with Thunderbird 78 only. It is not compatible with earlier versions of Thunderbird, nor is it compatible with current beta releases of Thunderbird.
• On Windows 10, the keyboard shortcut for pasting a clipping using its shortcut key has changed -- it is now ALT+SHIFT+Y. The old shortcut CTRL+ALT+V still works on Windows 7. The macOS shortcut Command+Option+V is unchanged.
• The option to show a prompt when pasting a clipping containing HTML tags into an HTML-formatted message is no longer available. If you had selected this option in previous versions, the clipping will now be automatically pasted as formatted text.

IMPORTANT!
If you've been trying out the previous beta releases, uninstall Clippings for Thunderbird first before installing this release candidate. Do NOT install this release candidate over a beta version -- this is an unsupported upgrade scenario, and will result in errors.
