[Typedef] created_by don't support space

[vemonet]

When parsing OBO files we are facing error when the "created_by: " of [Termdef] contains a space

For example "created_by: John Doe" is ok to describe a [Term] but not to describe a [Typedef].
But "created_by: John_Doe" works

The error raised is the following:
Parser: org.semanticweb.owlapi.oboformat.OBOFormatOWLAPIParser@####
LINENO: ### - expected newline or end of line but found: Doe
LINE: created_by: John Doe

Is it a normal behavior or should it take spaces?

Bug - according to the spec created_by behaves the same way for terms and typedefs.
