Misc fixes

- make it so '' is a legit password and doesn't unset the pw to pass bantu's unit tests (unit test could have been updated too but whatever)
- make it so not passing in any parameters to Crypt_RSA::setPassword() works without E_NOTICE or E_WARNING as per example in docs
- add missing phpdoc headers to File_ANSI
- cryan -> cyan in File_ANSI
