The EQI constants of the constants database did not match the ones used in the source up to now.
For whatever reason long long ago an array was created which mapped the const_db EQI constants to the source's EQP constant(aegis bitmasks).
With this commit we now use the already existing array from pc.h(which was moved from pc.c to be accessible).
This merges and closes#1147 due to follow up changes with 1cd3741.
