* Headers/Additions/GNUstepGUI/GSNibLoading.h: Added new method

nibInstantiateWithCoder: to do the initialization normally done
        in NSView when not in IB/Gorm.
        * Source/GSNibLoading.m: Added implementation of new method and
        also re-wrote part of NSCustomView.
        * Source/NSView.m: Added an NSAssert to assure that no subview
        ever decoded is an NSCustomView.
---
Moved decoding of custom view attributes here so that it can cleanly initialize everything to ensure that the view works properly.
