i added the svn:ignore for the new project that gets generated

Mark -  one thing I don't like is rules don't apply to the resources, so i have
to move all the pdfs to a sources block.  but, if rules did apply to sources, it
seem like I could get into a catch 22, in that the rule would be for pdfs, and
it would generate a pdf.  should i just go with it like this, or do you want to
update the xcode generate to let rules also run on resources but avoid the
catch?  (if we let rules apply to resources, we could also wire optipng or
something like that just as easy too)

LGTM as-is.  We can think about making rules apply to resources somehow.
