Equality Check doesn't consider enum properties

[Christian Oeing]

Doing an equality check for an enum should give the user a drop down to choose from the existing enum values when choosing "Constant" for the 2nd argument.

[Christian Oeing]

A drop down would require a special handling and a specific editor for EqualityCheck as both selections for the arguments have to be considered. EqualityCheck between a string constant and an enum value is possible now (Commit eb8f8426581cc7bb50a6193f80155bee8fa03bf5), maybe this is already good enough. The drop down would be just a bit more comfortable.

[Christian Oeing]

In general EqualityCheck should consider type of other value if "Constant" was chosen for one of them. This means using an IntField, FloatField, Toggle and enum drop down respectively.
