+ Support for overloading of Modelica element-wise operators.

  Now these are deduced from the scalar versions whenever necessary.
+ Normal operators can also be vectorized now if there is no other option.  
  That is: when there is no exact match found for operating on arrays but 
  there is/are some for corresponding scalars.
+ This is full support for operator overloading.
+ There are some deviations from the Specifications. 
  See comments in testsuite/records/OperatorOverloadComplexArray.mo and Static.mo
