5767f1f912 OperatorNode: Fix bug from wrong use of getIdentifier
1+(1+1) with parenthesis set to 'auto' triggered a bug because
getPrecedence gets the precedence of the content of a node, but
getIdentifier still returns the 'ParenthesisNode' identifier in case of
a ParenthesisNode.

2959858b99 operators: Use config when calculating precedence etc.
Use the parenthesis configuration to decide wether ParenthesisNodes
should be skipped or not.

8db07e23ad OperatorNode.toTex: BUGFIX: make clear where the exponent belongs to
Without proper parentheses it's impossible to decide whether an exponent
belongs to the numerator of a fraction or to the entire fraction.

For ConditionalNode, the exponent is hard to see without parentheses.

bbe22a9055 fix: no brackets with single operators (bug #273)
* Use brackets after unary minus followed by an OperatorNode with + or -
 - "-(a+b)", "-(a-b)"

 - "(a*b)!", "(a+b)!"
