Changed behaviour of Token::is*Op() functions:
...
- Rename Token::isOp() to Token::isConstOp() (indicating that the operator does _not_ modify the input variables)
- Create new Token::isOp(), returning true also for ++, -- and assignment operators
- Make Token::isExtendedOp() returning also true for all assignment and ++/-- operators
