Slurmpie

- Version numbers in sync

- Fixed tests

- Fix for using quotes in command by formatting command as a string.

Fix for typo in error message

Fixed double to single quotes for wrapped commands, should fix unrecognized commands.

Fixed compatibility with newer slurm versions:

- Wrapped commands are now in quotes
- slurm might give an error, but still return exit code 0. In those cases we now do display an error.
