PR/50114: Update py-mcomix to 1.01.

- Keyboard shortcuts can now be edited from MComix' preference dialog
  in a new tab "Shortcuts". (by Valentin Gologuzov)
  Please not that the arrow keys, Backspace and Escape cannot be bound
  to actions right now, unless you're manually editing the config file.

- During database upgrade, MComix did not consider that books in the
  "Last read" database might no longer exist, leading to program crash.
  This has been fixed.

- Adding a collection with a numeric name to the library made the library
  unusable. This has been fixed.

- Fixed win32 builds missing the 'calendar' module.

- Fixed bookmarks not being displayed in the Ubuntu Unity global menu.

- Fixed 'Continue reading' not working when files are opened from
  the command line (by Boris Bogar).

- Improved page extraction and caching algorithm, leading to much better
  responsiveness, especially for viewing large archives. (by Benoit Pierre)

- MComix will now always hide the mouse cursor after a period of
  inactivity, even when not in fullscreen mode. (by Benoit Pierre)

- The ALT+Left and ALT+Right keys will now either advance one page,
  or go back one page, depending on the user being in manga mode.

- CTRL plus mouse wheel will now zoom in/out one level.

- Manual zooming will now use a logarithmic scale instead of a linear
  spline.

- The library will now use natural sorting for "Sort by name" and
  "Sort by path" instead of alphanumeric sorting, bringing it in line
  with most other sorting done by MComix.

- Adding a book to a collection with the same book already existing
  in another collection did not immediately show the book in the
  library main view when the new collection was already selected.

- MComix can now use the '7z' executable to read .tar.xz and .tar.lzma
  archives.

- ZIP archives using BZIP2 compression will now fall back to external
  unzip/7z instead of failing (by Awad Mackie).

- MComix can now read PDF files using tools provided by mupdf,
  namely mutool and mudraw. (by Benoit Pierre)

- Double page mode will not implicitly resize images anymore.

- The smart scrolling algorithm has been improved.

- Some issues with the magnifying glass have been fixed.

- Some new variables have been introduced that you can use when running
  external commands. See the documentation for details:
  https://sourceforge.net/p/mcomix/wiki/External_Commands

- MComix will now use the current GTK theme's icons for
  Next/Previous buttons.

- Added AppData meta information for software repositories.

- Updated traditional Chinese translation (by Wayne Su).
