Refactoring notes

HWID
InfinityScript 1.5.3 has an entity field HWID which could replace a lot of DGAdmin code for getting the HWID.
However this field holds a 32 digit hexadecimal HWID which is completely different from the 24 digit hexadecimal HWID that DGAdmin uses.
The DGAdmin HWID does seem to work well, it keeps out some people with a HWID equal to zero, who are presumably hackers. While everyone I know does not have a zero HWID.
This left me 3 options:

1. Refactor it regardless, even though this will ruin existing permissions and may not work as well as the HWID DGAdmin uses.
2. Use both HWIDs, leading to more code and possibly more problems, but might be even better at stopping cheaters.
3. Leave it as is.

I opted for the third option here.
