Clipboard Manager: Added GUI and Clipboard History Feature

Summary

Added a full GUI for the Clipboard Manager that monitors clipboard text in real-time and stores it in a history file. Users can view, scroll through, and clear clipboard history from the interface.

Description

This update introduces a Tkinter-based GUI for the Clipboard Manager. The program now continuously monitors the system clipboard in a background thread and saves any new text entries to a persistent history file (clipboard_history.txt). Users can see the clipboard history in a scrollable text area and clear it with a button. The GUI updates are thread-safe, preventing freezing during clipboard monitoring.

The changes are as follows:

• Added a Tkinter GUI for viewing and managing clipboard history.
• Implemented real-time clipboard monitoring using pyperclip and threading.
• Added persistent storage of clipboard history in a text file.
• Added a "Clear History" button to delete entries from the GUI and file.
• Limited the maximum number of history lines to 1000 (configurable).
