Renewal of the CLI parameter --list-games

[ArcadeTV]

Possible integration of a renewal of the CLI parameter "--list-games" and dropping the parameter "--list-targets":

scummvm --list-games [additional options]

Outputs a complete list of supported games and additional data in xml format.

Benefits:
Users will have a rather comfortable way to check their datafiles while developers and frontend-people can utilize the data.

Data structure proposal (if applicable):

<?xml version="1.0" encoding="UTF-8"?>

[sev-]

While this is a viable request, we do not have that rich game metainfo in ScummVM. Thus, this simply cannot be implemented.
