Make -base compile almost without warnings again. Fixes:

- Using the correct format specifier
- Remove substringFromRange: (GNUstep extension) from NSString.h and use the non-deprecated version in -base.
- Delete definitions of methods that are the same in both a class and a category on that class (NSArray and NSObject).

Two files still have warnings:

- The GNUTLS stuff is using a load of deprecated APIs.
- xmlparse.m replaces a method using a category.  This method seems to always return nil.  Not sure what it's meant to do, or why it isn't a delegate of some kind.
