GNUstep Printing Backend Patch and such

[Chad Hardin]

I'm done with the first part of turning GNUstep printing parts into a 
"backend" type system.

Basically, what happens now is that every-time an allocWithZone: is 
done on a NSPageLayout, NSPrinter, NSPrintInfo, GSPrintOperation (not a 
type) , or NSPrintPanel,  that class instead calls a new class, 
GSPrinting, which loads up a Bundle located in Bundles/GSPrinting, and 
uses that Bundle's principle class to get the real Class (GSLPRPrinter, 
for example), allocates that and return it instead.

My tests have shown that printing works the exact same as before, no 
better or worse, which was my goal.  The only bundle that exists right 
now is GSLPR, which is basically all the code that used to exist in the 
NSPrint* and NSPageLayout classes.  Next will come the GSCUPS bundle , 
which will be a real stress test and will probably result in a bit more 
tweaking of both the NSPrint* and GSLPR* classes.

Anyhow, here is the patch and the additional files I added for 
everything to work.  It was suggested I share this with everyone before 
doing anything with cvs.  :-)
The Printing.tar.gz contains all the Printing backend budles, it 
contains the Printing directory and goes in the gui directory.
