rspamd-spamness

The add-on has been rewritten as a MailExtension (#22).

• This breaks compatibility with previous Thunderbird versions.
• The add-on requires full unrestricted access to Thunderbird for being able to maintain functionality that is missing in MailExtension API.

Notable changes:

• Rmilter support has been dropped as Rmilter has been deprecated a long time ago.
• Training buttons are missing drop-down "move/copy" menus. No time to implement.
• Default and per-account training folder settings has been changed. Each folder URI textbox is replaced by an account selector and a folder path textbox.

Known major issues:

• Currently MailExtension API does not provide support for message parts on demand loading. Thus, in order to get headers the add-on has to load full mail message.
• "Unexpected error moving messages: 2147500037" and "Unexpected error copying messages: 2147500037" while moving/copying messages with training buttons. Workaround: open a folder in the destination account before moving/copying (once per session is enough).

Migration from previous versions
The add-on does not offer automated configuration migration from the XUL extension. After upgrade you should tweak the add-on configuration according to you needs.

• Fix RGBA matching in theme detection when leading zero is omitted in Alpha channel (by @ichier)

• Added per-account folder location settings options dialog window that allows to set distinct ham/spam training folder URIs for mail accounts.
• Added dark Thunderbird themes and OS color modes support which is limited to the message header pane (background of the Rspamd symbols) as Thunderbird dark mode seems not consistent yet.

• Fixed moving/copying messages to "per-account" training folders from subfolders. In previous add-on versions per-account training folders worked only for moving/copying from the root folders and 1 level deep.
• Restored add-on options item in the context menu.
• Fixed groupboxes display in the main add-on options window.

• The add-on preferences tab converted to a dialog window.
• Now preferences in the main add-on options window are saved instantly after they have been changed.

• Convert to Thunderbird 68 compatible add-on (by @RemcodM). This breaks compatibility with previous Thunderbird versions.
