AutomationPattern: removed magic value at position zero

In automation patterns there always had to be a value at position zero
which also had a special semantic concerning the initial values of
connected objects. However that logic was buggy and confusing.
I therefore completely removed the neccessity for a value at position
zero (automated value will be 0 until the first set point).
