libcef:

- change 'void *' arguments to 'void* ' to match style requirements.

translator:
- add support for const virtual methods. (Issue # 36)
- output const vector argument types as 'struct _class_t* const*' (cons array, non-const members) instead of 'const struct _class_t**' (non-const array, const members) (Issue # 36)
- always add the 'enum' qualifier when outputting C API enum attribute types. (Issue # 38)
- update translated files.
