[Ifeffit] problems installing athena et al under ubuntu 16.04 LTS

[Matt Newville]

Hi Juan, Robert,

OK, I was able to reproduce the problem on a Fedora 23 Linux system with
the latest versions of Demeter and Larch.

I can see that the conversion of energy from eV to keV. Clicking different
combinations of the Numerator/Denominator buttons can alter the energy by
factors of 1000, and is not completely reversible.  I see a factor of 1000
as a multiplicative factor in the Energy Text Control window when "keV" is
selected, but this appears to not be editable.

I also see that this only happens when using the Larch backend and not the
Ifeffit backend.  And, I can also see that the energy is being set to the
very large value in Larch.  So that's a good set of clues to work with.
