Bug#779937: GDP shouldn't process all yaml files all the time

[Alexandre Detiste]

Package: game-data-packager
Version: 39
Severity: minor

Dear Maintainer,

When a user ask GDP to package some game,
GDP will read _all_ yaml files.

As the number of supported games rises,
it gets worse.

Running GDP without any argument also takes a very long time;
users may think it has hanged.
