iTerm2 3.3.10

What's new in this version:

Security Improvements:
- Improves the method for gaining authorization to run Python scripts launched from outside iTerm2
- Version 3.3.9 deprecated the older auth mechanism based on the command line, requiring the user to consent to every connection. That was annoying.

There are now two ways to get permission:
- The UI prompts on every connection
- The app requests a cookie using Applescript. Therefore, Applescript permission is required. This requires the user to consent only once per app that originates the connection.
- Note that this does not affect scripts launched by iTerm2, such as those opened from the Scripts menu

New Features:
- Updated shell integration installer UI, now with internet-free install option
- Add a setting to Edit Session to prevent Automatic Profile Switching from changing the profile
- Add support for opening files to line number with IntelliJ
- Applescript can now launch a Python API script from an absolute path

Improvements:
- Add a delay before previewing a color preset to make it easier to navigate the menu quickly
- Set SSL_CERT_FILE and SSL_CERT_DIR when running Python scripts so they can use TLS
