Using `gx` the currently selected file(s?) will get extracted,
automatically using the correct extraction program for the compression
algorithm and creating a folder if necessary to avoid a file explosion
in the current directory (all default features of the `atool` program
which is a dependency)
Added preview and opening of doc(x) files with nvim.
Makes use of docx2txt, catdoc to display the files, meaning they are
required.
Added some spellchecking words.
