ZamSFZ : built-in browser improvement

[trebmuh]

The storytelling:
When using the built-in browser to select a SFZ, one can navigate in the folders and choose a SFZ bank. All good here. One can play with this chosen SFZ.

Now, if I want to select another SFZ, I reopen the built-in browser which didn't record where I was formerly and I've got to re-navigate to the folder I was in previously.

What does I expect as a user?
I expect the browser to reopen at the same place I was, making the work-flow easier for testing different SFZ.

Hope that helps
