OLB: Define the scope specification from the UI

[tormoseng]

Currently, the scope specifications in OLB are entry point, database and synchronization. The first two works, but include predefined classes and methods, while the latter is only for testing purpose at the moment.

It would be really nice if the scope specification could become a parameter that one could specify in the UI. E.g. I want to specify a method-scope that looks for classes in the argument "org.something.*".
