Evolutions of file indexing

[Matthieu Gallien]

Hello,

Before more changes land related to file indexing, I would like to discuss 
where we want to go.

To me, we need to support two different ways to get music files depending on 
the platform support and local machine configuration:

* all music is already indexed by a supported platform specific indexer 
(Baloo, Tracker, Windows Search, Android media content, ...). We should allow 
the user to select that method that will be the fastest ;

* not all music is necessary indexed (removable device, network path, ...) or 
there is not yet support for the platform indexer (Windows, ...). In this 
case, we should automatically fallback to plain old file system indexing.

We could a configuration option to force use of plain old file system indexing 
if the user chooses so with a wording like that (to improve):

[Yes|No] Prefer use of fast search to discover your music (requires that all 
your music is already searchable)

In all cases, we would try first to get the metadata from the platform 
specific file indexer (like the dolphin metadata widget works).

What do you think ?
