Tachyon v1.4.1

Added

• View mode, for reading and copying rather than editing (#129). Ctrl+E, the "Toggle view mode"
  row in the command palette, and an EDIT/VIEW button in a sticky note's header (next to
  MD/TXT) lock the text: no block turns into raw Markdown, no caret is drawn, and typing,
  pasting, cutting, undo and find-and-replace change nothing (a one-line notice says "View mode
  • Ctrl+E to edit"). Dragging or double-clicking still selects rendered text and Ctrl+C copies
    it, a click on a link opens it, and task boxes still toggle. A sticky note remembers the
    setting across restarts, so a checklist note can reopen locked.
• Windows: "Open Default apps settings" in the command palette opens the page where Tachyon can
  be chosen as the default app for a file type (#123).
