Staticscope

[AsbjoernJC]

• Static scoping
• Added case to VisitSymbol to handle last case of exprnode
  This fixes stuff like:

bool changedDir = false;
int offSet = 5;

if(offSet>= 5 and !changedDir){}

• Added visit to blocknode in ifstatement
  This fixes stuff like not discovering undeclared vars in if block

bool changedDir = false;
int offSet = 5;

if(!changedDir) {
    offset = -offset;
}

• Added condition to test whether unvisited child are type correct

bool changedDir = false;

loop (int i from 1 .. 8) {
    if(i >= 5 and !changedDir) {
        changedDir = true;
    }
}

• Found bug in TypeCheckVisitor where operators set parent operator to && or ||. This is fixed which
  allows stuff like

if((1 + 1) == 2 != true and 0 == 0) {
}
