Add Keyboard Shortcut to Edit Playlists and Categories

📋 Summary

In LaunchBox, pressing Ctrl + E while a game is selected opens its Edit window. This request is to extend the same behavior to Playlists and Playlist Categories—letting users quickly open the edit dialog via keyboard shortcut.

🎯 Feature Overview

• While a Playlist or Playlist Category is focused in the sidebar, pressing Ctrl + E would open its Edit window.

• Matches existing behavior for editing games, improving workflow consistency.

🛠 Example Use Case

• A user is organizing Playlists and wants to rename or adjust metadata quickly.

• Instead of right-clicking and selecting “Edit,” they press Ctrl + E to immediately bring up the Edit window.

• Speeds up playlist and category management.

• Provides consistency with game editing shortcuts.

• Improves accessibility and efficiency for power users.
