mdcat-0.20.0

Added

• mdcat::TerminalCapabilities now exposes constructors for specific terminal emulators.
• Render reference link definitions as inline links if possible (see GH-149).
  This mainly affects image links inside inline links which get rendered as reference links.
• mdcat::Environment now contains all environment information required to render properly, namely the local hostname and the base URL.

Changed

• mdcat::push_tty now takes an mdcat::Environment instead of base_dir.
  base_dir is now part of mdcat::Environment.
• Image links now use purple foreground text (see GH-140 and GH-149).
• Image links render as inline links if the terminal does not support inline images and the image is not inside another link (see GH-141).
• mdcat::TerminalCapabilities now uses Option to denote missing capabilities.

Fixed

• Always treat links targets as URLs, never as paths.
• On ITerm2 only use the last segment of image URLs as filename for inline images (see GH-149).
  Previously mdcat used the full URL based on a misunderstanding of the Inline Images Protocol.
