 Everytime [https://travis-
 ci.org/isislovecruft/bridgedb/jobs/12651411#L1143 the `sha` module is
 imported], the following `DeprecationWarning` occurs:

 {{{
 DeprecationWarning: the sha module is deprecated; use the hashlib module
 instead
 }}}

 We should probably heed its advice. Unless something strange is being done
 somewhere with the `sha` module, we should pretty much be able to do
 `'s/sha\.sha\(/hashlib\.sha\(/'`.
