Introduction of BitWarden package + prep

+ BitWarden module for easy autologon (not very secure but convinent on
  personal machines) - Will think this over some more afterwards
* Get-Path will always return without trailing directory separator
  (might want to make this 'always' for dirs, but unsure yet)
+ Added Edit-MountUnit scaffolding for later modifying it to import a
  template on new mount units, and easy edit of systemd mount and
  automount units.
