Add more boolean comparison

[thoma01]

Add more boolean comparison that is supported with OPA.

Currently,

internal enum BooleanComparisonType
    {
        Equals = 0,
        GreaterThan = 1,
        LessThan = 2,
        GreaterThanOrEqualTo = 3,
        LessThanOrEqualTo = 4,
        NotEqualTo = 5,
    }

Add Contains, StartsWith and EndsWith. Seems all the calls are in place already, but aren't being used. Example CallContains, CallStartsWith and CallEndsWith.
