Filenames lower case; mod cron minute

This fixes a mismatch in case (which did not, but would have eventually caused a nightly build error)
I've also changed the cron minute so we can see if the correct cron job is being done.  It looks like the nightly build on dagmcci is running old code, even though I deleted the existing job and started a new one.  

I am going to wait a day before launching a new nightly build, and then we can look at the cron minute, which should be 25 past the hour.
