Updated Furnace+Forge version to 2.6.1-SNAPSHOT
FORGEPLUGINS-164 Restrict REST resource generation.

Only simple JPA entities are supported.

JPA entities with composite keys will be excluded from REST
resource generation. They will not be displayed in the dialog for
generation.
FORGEPLUGINS-120 Partial fix for composite keys.

This ensures that REST resource attributes mapped to composite
keys are not referenced in the generated AngularJS controllers.
Such attributes are also not referenced in the AngularJS views.
