Sorry, aritter, I have another for you. This is a fix to problems I introduced in PIPE2D-125. Would you please have a look?

    config: remove excess directory
    
    The directory has been removed (PIPE2D-125) but this change wasn't
    reflected in the config files.

    config: cleanup
    
    Remove blank and commented lines, unnecessary imports.

Why is e.g. `constructBias.py` still looking for config files in `config/pfs/`?

`root INFO: Config override file does not exist: '/Users/azuri/stella-git/obs_pfs/config/pfs/bias.py'`

Otherwise looks fine.
Note: I also updated drp_stella/examples/runPipeline.py and drp_stella/sphinx/user/getting_started.rst to remove `--camera PFS` after the changes to `genCalibRegistry.py` in PIPE2D-125. Did this straight on master though as it is pretty much only a documentation thing. Maybe should have filed a ticket though...

Also, there is still one file `constructFiberFlat.py` in `obs_pfs/config/pfs`. Missed that in the ticket PIPE2D-125 review...

The CmdLineTask framework looks in both config and config/pfs (because it has no idea whether there's two cameras in that package or not), and warns if either doesn't exist.

I added another commit to move constructFiberFlat.py down.

Merged to master.
