- bugfix (from build 529): IMPs have wrong voices

- bugfix: Multiple IMPs with same voice causes wrong data and CTDs. Now it is impossible to have multiple IMPs with the same voice. No more invalid IMP data with multiple imps (hopefully) ;)
- You can have a maximum number of 6 imps (3 women and 3 men). All have different voices
- If an IMP is cloned (90210, nickname) an unused voice is set. So we have correct data
- Prevent the user from selecting used voices in the IMP Voice selection screen
