convert 1.6 themes to 1.8

[Euan T]

I'm not asking MyBB staff to do this, but would it be possible for someone to write a small MySQL application that would spawn the templates into text files. Once this is done for both versions, a file compare program (ex. Beyond Compare) could be used to find all the differences in all templates.

That would certainly be feasible. I'll look into it this weekend.
