Update language names to match Google Translate (#33)

* Change language names to match Google Translate

This commit also fixes an issue introduced by commit 04a0e6df (issue #26),
where language names with underscores in them would not work, because
everything after an underscore is ignored.

* Add test for language names with spaces in them
