Title: Bug fix: -ext doesn't ever match lowercase extensions

When the command line is parsed, extensions are converted to uppercase
and placed in a dictionary. However, at comparison time, the actual extension
is not uppercased, so lowercase file extensions never match and are always
output into the Paraffin output file.

I did not check the other exclusion functions to see if they have a similar problem.
