fix/cleanup(div): switch to using `faction` wiki var instead of `race` wiki var

[hjpalpha]

Summary

• switch to using faction wiki vars instead of race wiki vars
• additionally it fixes a compatibility bug with HDB
• currently HDB only sets faction wiki vars while most modules still expect the race ones
• this PR switches all git components to use the faction ones instead and hence fixes the above mentioned issue
• clean up some (lua) variable names

(Non git modules & templates should by now be able to work with both vars, after this PR i will remove the support for the race one)

How did you test this change?
