Rename the "Reload from Musicbrainz" option in the context menu

[jus]

Tested with lp:trunk

The "Reload from Musicbrainz" option in the context menu is pretty much non descriptive and should be changed to something like "Get Track Metadata" or "Lookup Metadata online".

Why?
Because it describes what the option actually does. It also implies that an online connection is required. Most users dont care what kind of online service we use for retrieving the data as long it is reliable, so attribution is not even required at this point.

hm then we should also change the 'Reload Track Metadata' to something that makes it clear that they are reloaded from the file.

Actually I would also remove both from the context menu and only make them available in the properties windows.
This makes the context menu nice and small plus track metadata can't be changed by accident

Here is a small patch that does the following:
* Add separator in the context menu to group metadata related menu points
* Rename available options to "Reload Metadata from File" and "Get Metadata from MusicBrainz"
   Since all options in this menu are somehow related to a track, it was reasonable to drop the extra
   "track" from both menu points.
  In response to #1, I would like leave both options in. Mostly for the reason that you can reload
  metadata from multiple files, something you can't do with the current property editor.
* In the MusicBrainz fetcher dialog:
   - Add descriptive Title to the dialog window
   - Add some translator comments
   - Change Song -> Track
   - Change button order to be like in the Tracks Properties dialog
   - Use Ampersands (&) for button text to quickly access that particular GUI element.
   - Fix tab order.
* In the Tracks Properties dialog, metadata buttons are now in the same order like in the context menu. Also fix tab order.
