Change default playback-order from "shuffle" to something more intuitive

[Simon Steinbeiß]

Currently the default playback-order in gmusicbrowser is set to "shuffle". This is very surprising for new users, as we found out when collecting feedback from Xubuntu users lately.

So I propose to change that (it's very easy to do that via the gmbrc.default file) behavior to something that is more intuitive. The main reason being that the default visual sort-order (which is not necessarily in sync with the playback-order in gmusicbrowser!) isn't "shuffled" either, so in my opinion, the default playback-order should ideally match the default visual sort-order.
As to the proposed new playback-order: I've personally always worked with "path album disc track file" – adding "path" and "file(name)" as sort-criteria improves behavior for files with bad tags.

I'll add a patch to this bugreport shortly, it's basically three lines changed within gmbrc.default to set the new default playback-order – so the decision about this "bug" is actually more a "philosophical" one than a technical one.

This sounds sensible to me. Since gmb can have names for sort orders, please also consider naming default sort order simply "Default", if it isn't already.

The patch I'm linking to here also adds "remember playing song" to our default settings, which complements the playorder-changes in my opinion.

Furthermore I activated the album-info plugin by default in this patch, because we have it in our default layout and not setting this option makes it just an empty tab.

As the patch is very verbose, it should be easy enough to only pick those parts we can all agree on.
