changing default output of Hebrew docs to pdflatex

[Scott Kostyshak]

I can now compile all Hebrew documents with both ps2pdf and pdflatex.
When I compile with luatex, I get the following error:

<<
To avoid this error message,
run TeX--XeT or e-TeX engine instead of regular TeX.

! Right-to-Left Support Error: use TeX--XeT or e-TeX engine.
l.77      engine}

I will set pdflatex as the default output format, unless someone objects.
