[Aavso-photometry] FITS Keyword List

[Michael Newberry]

Of course it's not rocket science. We do that in a number of places in Mira. 
For example, in the photometry package, there are 9 keywords who's names can 
be specified, and the Change Keywords method in the Image Calibration tool 
can setup a collection of keyword names to change and values to set and then 
save that as a "profile".  But I really think it is best to consider keyword 
translation as being a fix rather than some type of routine task.
