(2x) Replaced String[] by an Enum:

The available fit methods and their accuracy are now represented by an
Enum instead of String[].
Display a map of ln(a) instead of a:

A shows high variations. That it is why one has problems setting up
brightness and contrast. Using ln(a9 reduces the variations and makes it
easier the review the map.
removed ".0eV" from elemental map label if there no is decimal place:

Now I use MessageFormat to create the label, which solves the problem.
But now the formating depends on the current locale. I will address this
issue later on.

"width = input.getHeigth()" was used instead of "width =
input.getWidth()".
Changed the String at "IJ.run()":

After changing plugins.config i did not update this String.
