Duplicate Region Tags

[RibShark]

There are various region tags that appear to be duplicates of each other with no rhyme or reason as to which is used:

• USA, Asia/Asia, USA
• Asia, Europe/Europe, Asia
• Japan, USA/USA, Japan

It would be a good idea to consolidate these together.

Additionally, "Europe, Germany" makes little sense to be a region tag of its own considering only one disc uses it and a "Europe" tag should suffice ("USA, Germany" and "Australia, Germany" also seem like they could probably be consolidated into their Europe counterparts).

Also, what is the use of the "Export" region?

Cleaned up the tags to the ones that had more entries
Moved:
Asia, USA -> USA, Asia
Asia, Europe - > Europe, Asia
Japan, USA -> USA, Japan

And moved the one Europe, Germany entry as it is pointless (Two Europe regions = Europe region, not Europe, Region)
Europe, Germany -> Europe

I requested iRobot to delete the empty tags
