Add setting for LSUIElement

The way I use iTerm2 is by having a shortcut combination that shows me the iTerm window, coming up from the top of the screen, at about 30% height, with some transparency. Because of this, I don't want to have iTerm appearing in my open apps when hitting CMD+Tab.

I always go to the Info.plist file and I add:

	<key>LSUIElement</key>
	<string>True</string>

This allows me to work with iTerm2 the way I want to.

The problem is this setting gets reset whenever I update iTerm2.

Would it be possible to have this behaviour somewhere in the application settings, and ideally have that saved between updates?

(Not attaching any files because there's no need to do that, not really a bug request, more of a feature request).
