AC-1754 ERXExistsQualifier was doing a global replace of the key in the select statement but should have only replaced once. Without this fix, we cannot reliably chain ExistsQualifiers.

Modified table alias matching code to avoid incorrect matches when Postgressql. When trying able alias declarations for t4 and t8, it would also match variable bindings for that had a datatype of int4 and int8 e.g., “?::int8” and “?::int4”

Fix a NullPointerException when calling the EOModel.createPrototypeCache method from the wrong EOModel

The `ERXModelGroup` class may create duplicate models in some cases. They are not added to the model group, but their presence may cause problems. The root cause of this problem is related to the duplication of `NSBundle` references while loading `EOModel`s. This fix uses a `NSMutableSet` instead of a `NSMutableArray` to hold the references to all loaded bundles. It avoids the presence of duplicate bundles and therefore the presence of duplicate model references.

One can find more information about the issue at the above link.
