[TIMOB-24462] Decouple liveview from Appcelerator Studio

The docs state that liveview is bound to be used with Appcelerator Studio. I am not using Appcelerator Studio for the simple fact that it is hellishly slow: the frequent project indexing, opening files, tiapp.xml editor, dashboard... most of the functionalities are sub-par and I'd therefore prefer using a proper editor like PhpStorm. However, the *--liveview* directive does not seem to work by itself when I execute the build command like *appc ti build -p ios -T simulator --liveview*. I've had it working in the past _without the use of Appcelerator Studio_, by reasons I could not explain (possibly installing the Appcelerator Studio changed some config settings in the CLI?). I am a 100% sure using the studio is not a technical requirement. Having the --liveview option available to everyone is a requirement though, because development is already slow enough using this platform. Replacement modules like TiShadow, and buggy implementations like [here](https://jolicode.com/blog/alloy-selective-compilation-for-an-even-faster-titanium-development-process) arent an option since they're 1) hard to implement 2) underdeveloped and 3) buggy. I wonder what Appcelerator's view is on this.
