v0.6.0

Added

• Text copied from a web page, an email or a document is pasted in Editor mode as Markdown:
  headings, bold and italic, links, lists, quotes, code, images and tables kept, the page's
  layout left out (not in a table or a code block). Ctrl+Shift+V pastes the text as it is.
• Preview mode, the second of the note's modes between Editor and Source: the note rendered as
  GitHub renders Markdown (alerts, tables, tasks, footnotes, bare URLs linked), read only, in
  the light or dark style and the note's fonts and size; its links open notes or the browser,
  the outline goes to its headings; wide tables and code blocks scroll sideways each on its
  own, their scrollbar in sight, as in Editor mode. Notav now needs WebKitGTK 6.0.
• Ctrl+1, Ctrl+2 and Ctrl+3 switch the note to Editor, Preview and Source mode.

Changed

• The view menu's text size, Wrap Lines and Full Width are each mode's own (Editor, Source,
  Preview), all starting as they were set.
