features: disable remove bundle and kill running app

[rob-miller]

Thank you for saving me from Xcode's 'file 2.swift' creations while using Xcode and vscode simultaneously.

Some feature requests:

• I am developing my app on my personal iPhone, and have used the app for some years. Clicking the 'SweetPad: Remove bundle directory' would be a very sad thing for me, as it would delete my years of personal data inside the bundle (yes, I do have backups but they are not auto-generated so possibly not recent). It would help if there were a setting to turn off / disable / hide this button.

• I miss the button on xcode to kill the running app (obviously I don't use the button above).
