Focuses the project tree view on the active task, only displaying relevant files/paths.
General usage instructions
This adds a "Focus on Active Task" toggle action on the View menu. Use it (Ctrl+Shift+Q is the default shortcut) to filter your project tree with the currently active task/opened files. Filtered paths will be marked as such ("Filtered") on the tree view. Once enabled, you can also Alt-click any filtered folder to temporarily unfilter it and show all its children (Alt-clicking on empty space will unfilter all top-level nodes).
