Extract trait data

[CptToucan]

We want to be able to show what traits do to the user. So we should extract this data from the ndf.

In UniteDescriptor.ndf you can find the TCapaciteModuleDescriptor which lists all the traits the unit has.

You can find these then in CapaciteList.ndf for the aura it takes effect, and then you can look at the TargetEffect and find what it actually does in EffetsSurUnite.ndf
