Script: Protein Dictionaries (rename and update)

Wrote a script that returns dictionaries that translate DNA and RNA to
protein.  Deleted the old RNA to Protein script since the functionality
is included in the new script.
Translating RNA into Protein (syntax update)

Updated to use the new protein dictionary script, as the old one no
longer exists.
Inferring mRNA from Protein (syntax update)

Updated to use the new protein dictionary, as the old one no longer
exists.
