Preparing for expansion of new features

This is a small update that prepares for expansion of new features

It places the delete button inside of a menu. While this does nothing now, it allows more items inside the menu. Planned features include:

• Export & Import various data snippets like Pokemon or Locations to it's own JSON file that can be saved as backup, handed to someone else, or even usable by another editor outside of this one such as websites.
• Quick actions like Auto-Heal or Increase Level
• Countless other features are planned

This creates room for the new incoming features.
