[Mozile] Problem with path for rng

[James A. Overton]

Meg and everyone else,

I've fixed the mozile.useSchema() problem and committed changes to  
CVS. While fixing the problem, I made a change to the way  
mozile.useSchema(path) calculates paths: relative paths are now  
relative to the mozile.root path, like the other path arguments in  
Mozile functions.

This change will BREAK older configurations. All the Mozile tests and  
demos have been updated, but you will have to change the  
configurations any other files you've created. For example, in  
basic.html the code changes from
	mozile.useSchema("../lib/xhtml.rng");
to
	mozile.useSchema("lib/xhtml.rng");

Once that change is made, everything should work...
