also adds a base implementation that most signal sources should inherit from. The gen_signal_source is inexplicably different (probably as a test fixture, commonality was not valued). Only the file_signal_source has been tested; all the sources are modified in the same way, but we all know the only proof of correctness is testing. The block factory was simplified a bit. Handling for legacy config files was pulled out of the flowgraph; now when the "0" instance of a component (Foo0) is created, if there is no config for it, then the legacy version (Foo) will be tried. This is different from passing -1 for the item number (which is still supported). Theoretically, all existing config files should still work.
