Directory reference bugs

[hile]

You seem to be using same 'current directory' reference pointer in multiple places somehow, and this creates most interesting bugs.

- Go to a album sub folder in the side panel, does not matter which folder
- Press 'dir' button to analyze full tree: observe current side panel path shown in analyze window's path
- Click on analyze window path to change it, observe the path actually changing to last directory you scanned, not current directory as it was shown!
- After finishing analysis, close the dir analysis normally from 'ok' button
- Still seeing the album sub folder in side panel, go there and press the 'go to parent directory'
- you actually end up to the parent directory of analysis directory, in my case root of 'Data' filesystem

So, quite obviously same variable is used internally by these two parts, and the variable 'leaks' from different parts of the UI to the other. Please use separate variables, this can be very confusing! I have seen this error in other places as well ('save/load playlist' etc affects other parts in the UI), but this one was the most obvious example.
