IDI Operations: Always Start the IDI Server and CE with the "-s" Flag

Keeping it simple, you should always start the ibmdisrv or ibmditk processes with the "-s" flag to specify the solution directory to use. If you don't do this, then you're just using whatever happens to be set in your environment, which could lead to quite a bit of confusion. As an example, you could have your CE (the eclipse IDI GUI) running with a DIFFERENT solution directory than your Default ibmdisrv process. This could lead to a case where properties that resolve perfectly in the GUI don't resolve when you go to run an AL. You can avoid this by always using full paths to properties files, but then that makes your solutions much less portable.
