I've taught the server-side hook to have custom limits on a per-type
basis.  Now .c files can be up to 3MB and .cxx files can be up to 2MB.
If this still proves too limiting we can make the limits bigger for
specific file types while still enforcing it overall.

I choose to be very conservative here.  While converting history from
CVS I removed several very large files (like a PowerPoint presentation
full of large images) that should never have been committed.  Back in
the CVS days such large files could be simply "cvs rm"-ed to prevent
developers from having to download them on checkout.  Now with Git once
they are in history they are there forever and everyone will always
have to download them.  It is better to prevent them from being added
in the first place.
