Use consistent language + script naming convention

The Detect languages table is apparently showing Translator system-internal names with underscores, rather than the actual language names.  The edit changes these to proper language names according to the convention. this clarifies the ambiguity in "Haitian_Creole" -- where "Creole" is part of the name, not a script as it is in other identifiers.  I would ask that for consistency, you also show the language codes that the Detect API returns for all of these. I assume that the API returns proper ISO codes, and not these internal ids with underscores.
