Simplification without encryption

The package has been completely rewritten. Among the changes:

• Password encryption has been removed as it does not provide sufficient security, but is too complex
• The package now runs on Python 3.8 for Sublime Text 4
• clear_on_remove setting was removed
• Added a pure_PuTTY_enabled setting that adds a new option to the nav-bar if you want to just open PuTTY without any session
• The path is now displayed at the top when Choosing folder

Various fixes, including:

• The pure_PuTTY_enabled setting can now fully accept a list of strings list[str], e.g. ["putty", "-C", "-2"]
