Add papis config file. Sets up a single 'academia' library in Nextcloud/Library folder.
Uses vim for most editing, and vifm as the file manager. No advanced functionality of papis is touched yet.
The structure of the library is to use authorname-title as subfolders in the library for the individual document clusters (i.e. the info.yaml files and any associated document files or notes).
Will need to further test functionality.
