File paths are stored as absolute paths in db

[busybit]

I saw that paths to the music files are stored as absolute paths in the library database. Wouldn't it be better to store them as relative paths, relative to the base directory of the files (as set in config).

That would allow easy moving the files to some other location. I store my music files on a NAS and sync them via bittorrent sync to some pc's, where they are stored in different locations. The database is inside the music folder and is also synced. Relative paths would allow me to store the music in different locations.
