[caesar] cipher files renaming

- removing mode information from filename
- getting ready to have different modes called by constructor argument
- folders now reflect the precise cipher name
- filenames and classes are UpperCamelCase
[caesar] OCB added

- OCB cipher with 9 different modes
- linking against OpenSSL now :-(
- static linking in release mode disabled due to OpenSSL problems
- small fix in status processing during project initialization
- added ALGORITHM_MODE to CAESAR configuration
