- FIX: File browser "This PC" section empy

- FIX: File browser "Path incorrect" error on multiple folders selected
- FIX: File browser allowed addition of incorrect file share paths (will now throw an error when the path does not exist)
- Changed: Some changes to the UI for the file browser (no more dropdown select for "This PC". Instead a "localhost" entry is now added to the tree selection
