Message:

• added feature to add a callback function to configvalues. they get called if the value changes. an examples is in Core.cc.
• changed the SetConfigValue macro and the Identifier::updateConfigValues() function to work properly with inherited classes in both possible cases: 1) they overwrite the config-value or 2) they don't. an example is ParticleProjectile that defines it's own speed_ configvalue.
