RastaConverter1.0-RC8

• Fixed the in-conversion rate graph drawing semi-transparent diagonal lines
  across its data. The area below the non-convex curve is now rendered as
  adjacent strips instead of an invalid convex polygon.
• Made Zoom to recent show a distinct, full-resolution two-minute window. The
  control remains disabled while the whole run already fits in that window,
  instead of changing only its label without changing the graph.
• Recent Conversions cards now have an x action for removing one conversion
  from the library. Its confirmation can optionally delete the output folder,
  retaining the existing rc-... folder-name safeguard used by Clear all.
• Moved the GFX/TEXT, NORM/WIDE and DUAL badges to a left-aligned stack in the
  top-left of each Recent Conversions thumbnail, opposite the removal action.
