Building Vdbs in eclipse should not throw runtime exceptions

When the VdbBuilder is initialised, it starts looking for all the vdb files in the workspace and synchronizes them and other housekeeping tasks. Such tasks involve the creation of a Designer Vdb pojo which uses the OperationUtil.perform(Unreliable) method.

This method will throw a runtime exception if an exception occurs within Unreliable's operations. However, should an exception be thrown, all building in Eclipse will cease as a runtime exception is not handled by the BuilderManager.

Runtime exceptions in this case should be replaced with normal exceptions which will be properly handled in code and allow other builder tasks to continue.
