Umlaut handling for gametitles

[nex86]

Sony's UI cannot handle umlauts, so game titles with umlauts will be displayed as
"Der Knig der Lwen" instead of "Der König der Löwen"
to handle this, umlauts have to be renamed like the following:
Ä=OA
Ö=OE
Ü=UE
pretty sure there is other languages that have more umlauts, but in for German it would be just the three.
Guess this can just be done with the same method as how commas are handles, just for title names this times.

In Polish there have 8 cases like that ... good news there are no games with polish titles :) ... In general this is a bit weird - wonder how the JAP region console works, as this clearly shows UTF8 is not supported by the UI and JAP PSC probably shows latin names instead... btw there is another one in German "ß" but I do not think was used on any game. I will preprocess titles in the AutoBleem to remove all non ASCII characters in game titles... need to find out a CD with german version of Lion King to test it
