Noel Grandin 60bc263547 new loplugin:conststringfield
Look for const string fields which can be static, and
mostly convert them to OUStringLiteral

And add a getLength() method to OUStringLiteral to make
the transition easier.

Remove dead code in XclExpRoot::GenerateDefaultEncryptionData,
default password is never empty.
