Modifications for the backend printing bundle system.
* Headers/Additions/GNUstepGUI/GSEPSPrintOperation.h: added.
* Source/GSEPSPrintOperation.m: added.
* Headers/Additions/GNUstepGUI/GSPDFPrintOperation.h: added.
* Source/GSPDFPrintOperation.m: added.
* Headers/Additions/GNUstepGUI/GSPrintOperation.h: added.
* Source/GSPrintOperation.m: added.
* Headers/Additions/GNUstepGUI/GSPrinting.h: added.
* Source/GSPrinting.m: added.
Split off the various PrintOperation classes. This makes is clear that
the printing backend bundles subclass GSPrintOperation, not NSPrintOperation.
Also, GSPDFPrintOperation will probably become large when implemented, this
clarifies the class structure and prevent NSPrintOperation.m from become
overly large and confusing. The GSPrinting class is helper for loading the
proper printer backend bundle.
* GNUMakefile: includes the Printing directory.
* Printing: Added the printing bundles home directory.
* Printing/GNUmakefile: added.
* Printing/GSLPR: Added the first printing bundle.
* Printing/GSLPR/GNUmakefile: added.
* Printing/GSLPR/GNUmakefile.postamble: added.

Here it is, the first backend printing bundle, version one. The are very
little code changes from the original source, bugs that may have been
present there would have been carried over here. However, this is just the
first round. This bundle uses GNUstep's original PageLayout and PrintPanel
GORM panels, it does not have its own. Hence, it is very simple. The plan
is for the future GSCUPS bundle to also use GNUstep's GORM panels, not for
each bundle to have their own panels.
