Fix conflicting file load

requiring 'eBay.rb' loads any ebay.rb file you might
already have in the load path, although possibly only on
case-insensitive filesystems.

Probably not a common problem, but one we're facing.
Don't double load files

Ruby's require statement uses the string you pass it to tell if the
file/library has already been loaded. Switch the second require
'eBay.rb' statement so it uses the same pattern as the first and the
library doesn't load the eBay.rb file more than once
