Fixing --with-doxywizard option in doxygen formula

Currently, the --with-doxywizard option does not build or install doxywizard.  This pull request fixes that.

I had to patch the install target of the relevant Makefile.in for the proper place of the doxywizard binary.  This is similar to what macports does.  See:
