summary:     eliminate some macros in version.h

Appears to have gotten rid of OCTAVE_API_VERSION_NUMBER from version.h.  It
appears that at least swig uses this macro in #ifdefs to handle changes in the
Octave api and this is breaking swig generated code for octave 3.8.0 (see
https://sourceforge.net/p/swig/bugs/1353/).

Is there a particular reason for this change?  Is there a better way to check
API versions?  The text string OCTAVE_API_VERSION is a lot harder to parse.

Thanks,

  Orion
