Alpha-Commit: Adds a task that can be used to convert to formats like PDF

Adds a task that can be used to convert Markdown files to formats like
PDF, Docx, etc. using Pandoc.

This new task with a slightly different structure is needed, because
Pandoc only supports the `-o <output_file_path>` for formats like PDF,
Docx, ...

This new structure still needs thorough testing. Also there is a problem
of Pandoc with Texlive on Windows that sometimes can hinder the use of
this upgrade.
