#245 IfTask does not add IsGreaterThan and frieds

[Stefan "Bebbo" Franke]

You need to add to IfTask.java:

public void addIsGreaterThan(IsGreaterThan e) {
super.add(e);
}
public void addIsLessThan(IsLessThan e) {
super.add(e);
}
public void addIsPropertyFalse(IsPropertyFalse e) {
super.add(e);
}
public void addIsPropertyTrue(IsPropertyTrue e) {
super.add(e);
}
