Remove loadConfig()

The loadConfig() function is mostly the same as getDefaultConfig(),
except that it calls loadUserConfig() and stores the results in
originalUserInput.

This refactoring commit replaces the loadConfig() call with
getDefaultConfig() and loadUserConfig(), which allows deleting a large
amount of duplicated code.
