A few tweaks to fix issues I've been having with Tales of Symphonia in 

safe texture mode. One, don't hash the palette when it doesn't matter;
including it completely kills performance in the map mode, and I'm 
pretty sure it's because the palette points to essentially random 
memory.  Two, include the address in the hash seed; this helps with an 
issue related to the EFB and the main menu.  Hopefully, these changes 
together don't cause any regressions.
