Run custom script at end of night

[Alex-developer]

Allow a custom script to be run during the end of night processing. The script is run prior to the deletion in case you want to do something with the images before they are removed, as in my case where I am archiving them to a local ssd

Hey Alex, I like having a place for custom code that's separate from the main logic. What about having an empty endOfNight_additionalSteps.sh? That way it wouldn't require any addition to the config file and would be less prone to a path error.
My thought here is to try to keep the config file quite general (options that most people want to use) and small enough to be readable.

Makes perfect sense :-) If people did want to keep the scripts outside of the allsky directory they could just call their script from the endOfNight_additionalSteps.sh.

I'll modify the pull request and add the additional script.
