Documentation: make it clear that ** is no longer required for recursive class lookup

[xunnanxu]

Currently most of the documentation says .* will tell ebean to look for all classes under the specified package. However this is not clear enough as in Java the word "package" mean no recursive lookup. Hence the doc should be fixed. "Directory" is probably a better word or "recursive" should be explicitly mentioned.

Also the ebean documentation should probably be revised in the same manner.
