Add filterManyRaw() and Deprecate filterMany( <string expressions> )

The filterMany( <string expressions> ) uses the language parser which
ultimately will we probably remove in ebean 15.x

Code can migrate to filterManyRaw() instead or better yet change to
use the improved query beans filterMany( <closure> ) option that will
be included in this same ebean release.
