Fixes:

• Workspace root layout mode is now restored correctly

  workspace

  different workspace instead of only the same workspace name as it had
  originally
• Added ls command for listing saved workspaces/profiles
• Added rm command for deleting saved workspaces/profiles
• Added -n/--numeric option for specifying workspace by number instead of name
• Floating windows are now supported
  • As a result, the scratchpad can now be saved/restored using
    i3-resurrect save/restore -w __i3_scratch
• It is now possible to interpolate cmdline arguments from the actual process
  into custom command mappings
• Programs that are already open in the workspace will no longer be restored
