Make any app developed using the adl_workbench code-base look for a .cfg file in the cfg location of adl_workbench. I.e. let it reuse the adl_workbench config file if there is none of its own. Probably this system has to be tightened up in the future a bit since mutiple writers could do bad things to the file, but for the moment, there is only one writer app - AWB, the others are readers.
