Review request for Amarok.


Changes
-------

Discovered that relative paths processed separately in each playlist type.
I've moved this processing to  PlaylistFile.


Description
-------


I've started my changes with an implementation of a ASXPlaylist class,
due this work I've found that implementation of different playlist file
types has different logic, as result I end up with a rewriting
playlist's implementations.

As example of difference:
  -- Constructor M3UPlaylist::M3UPlaylist( const KUrl &url ) sets a url, but
     does not load playlist, therefore loading of playlist are
posponed till data from playlist are actualy needed (lazy loading)
     On the other hand constructor XSPFPlaylist::XSPFPlaylist( const
KUrl &url, bool autoAppend )  loads playlist.

The main idea of proposed changes is to create a unify code for
processing playlist files:
  -- lazy loading through LazyLoadPlaylist
  -- common functionality was moved to PlaylistFile.

It is worth to be noticed that this patch changes structure of
playlist's classes, bit does not changes their behavior, even if this behavior
is inconsistent in some cases.

In following patch-requests I plan to submit ASX Playlist parser and
organize playlists processing in more consistent way.

Testing
-------

1) All unit-tests were passed.
2) For all playlists I've also checked loading and
   saving through gui.
