Additional number formatting for much larger numbers

The existing number formatting for names and initials stop at "septillion", but many players (including nearly anyone with 1 million or more HC) regularly deals in numbers orders of magnitude larger than this. It's a trivial matter to handle larger numbers than this in these two formatters, simply add new names.

I would have also updated the SI unit abbreviations, but I can't find a reliable source for what they should be, and the few random sources I can find do not all agree.
