Opportunities (Kansen in Dutch) change too many fields when editing

[aad@almende.org]

When editing an opportunity the first time and changing the scoring chance (scorings kans in Dutch) and then save it, it is saved and when opening the same opportunity for a second time the new value sticks. However, if i open the opporunity again and change e.g. the expected closing date the scoring chance changes as well. This is both unexpected and unwanted behaviour.
