A Note on Custom CSS

This update includes a full refactor of the theming: The editor themes (Berlin,
Frankfurt, Bielefeld, Karl-Marx-Stadt, and Bordeaux) have now moved to their own
theme files and do not come with standard CSS anymore. This heavily un-clutters
the codebase, but it may impact your Custom CSS, should you use this feature. We
have ensured that no class names change and that the styling is mostly the same,
but the possibility of having to adapt the Custom CSS may arise for some of you.

GUI and Functionality

• Fixed a visual issue that would handle overly long window titles improperly
• Fixed Tab not indenting/unindenting code in the CodeEditors (snippets,
  profiles, etc.)
• Fixed a precedence issue that would make it impossible to use autocomplete
  while filling in a snippet; now, accepting a potential autocomplete has a
  higher precedence than moving to the next tabstop of a snippet, making working
  with snippets more ergonomic
• Images now render more appropriately in inline-contexts
• Updated the German translation
• Fixed the keyboard shortcut for inserting footnotes on Windows and Linux
• Removed the accent color setting: now the accent color will always be the
  system accent color on macOS and Windows, and Zettlr's brand green on Linux;
  themes do not provide an accent color anymore
• Restored syntax highlighting for inline math code
• Fixes an issue that would frequently may make the cursor appear to jump or a
  dialog appearing warning of external changes (#4729; #4732)
• Added some translations
• Generating link previews no longer downloads the entire link target if the
  content is not preview-able
• Improved layout of link previews
• Overly long summaries of link previews are now shortened
• Project properties now adequately resolve the readers and writers of the
  existing profiles, enabling the usage of profiles with extended
  readers/writers (#4699)
• GraphView's labels are now rendered filled instead of stroked, to make it
  easier to read the labels.
• The GraphView does now support multi-window, so clicking a link will open it
  in the last focused window. If the file is already open in a leaf, that file
  will be in that leaf, otherwise it will open the file in the last focused
  leaf.
• Alt+Click in GraphView will force the document to be opened in a new tab.
• Zettelkasten links and tags will now be output by our custom Markdown-to-HTML
  parser (i.e., in various places in the app as well as on Copy with Style)

Under the Hood

• Moved all themes from the *.less-files into proper theme plugins for
  CodeMirror v6; this means that they will not provide any global styles
  anymore; any applicable styling has been moved to more appropriate places
  (CodeMirror plugins as well as the WindowChrome and the various remaining
  *.less files). We tested the changes out and in our settings, no changes
  were necessary; sometimes you may need to adapt class definitions
• Remove unused color variable definitions
• Move gray color palette to the Window Chrome component
• Fixed an issue where the font definitions were borked and required usage of
  !important to make them work (#4719)
• Upgraded all available CodeMirror components to the most recent version
• Replaced fs.unlink with fs.rm in safeDelete to support recursive removal
  of directories
• fsal-directory::removeChild now calls pathExists instead of isFile to
  make sure directories also are removed in removeChild
• pathExists wraps fs.promises.access.
• (CodeMirror) Move plugin-specific base styles from the main override as well
  as from the themes to the respective plugin files
• Bump Pandoc to version 3.1.9
• Fixed a weird layouting issue with the code block backgrounds
• DocumentManager's openFile does now handle the case when windowId and leafId
  is undefined, by keeping track on the last used editor.
