MacGui: Fix how we get the current instances pid number since NSRunningApplication is a 10.6 only api and therefore breaks 10.5 compatibility (which also borked the nightly build).

- Many thanks to ritsuka for pointing this out.
- Also adds ability to get the full path to each running instance if we need it in the future.
- Note: Adds additional logging to hbInstances which can be removed when we see fit. But for now imho could be useful since we are early in multi-instance queue encoding.
