Playlist album selection enhancements

[eric-gilbertson]

The new album lookup in the playlist editor is very helpful. Suggest the following changes in order to make it even easier to use:

• display artist's albums by time (new to old)
• reduce track top/bottom padding in the album track list box
• change pages's default entry mode to "Manual"
• restore previous entry type upon return from the track edit mode (current behavior is to reset it to the first entry type)

Together these changes reduce the number of keystrokes required to perform the most common playlist operation, eg adding a track from an artist's latest release. Possible future enhancements in addition to these include smart page updates following a save and allowing artist name lookup using "first last" name format, eg Ray Davies.
