FlexPlaylist 0.4.8 (0.5 prerelease)

Changes since 0.4 include:
- Autoresize columns, time takes as much space as needed, title column takes the rest
- Show number of playlist items in statusbar
- Add action to remove a file from disk
- FIX: Back action in random playlist mode (backported from splitplaylist)
- FIX: Show error when saving playlist failed
- Added action to go to currently played song (handy for large lists)
- Massive speedup on clearing playlist (don't update statusbar for every removed file)
- lots of code cleanups (less debug output, less old commented code and unused methods *oops*)
- Temporary messages in statusbar for loading/saving playlists
- Don't add files to playlist that can't be played by Noatun (needed for adding whole directories)
- Greatly improved filters for fileselectors, now allows to filter for certain playlist formats

Changes since 0.3 include:
- Removed small windowborder, it removes the taskbar entry too and causes
  focusing problems with dialog
- Added "jump to" Dialog
- Added player toolbar, it contains the same items as "Player" menu by default
- Ported lists context-menu to XMLGUI
- FIX: let Noatun handle removal of PlayListItemData
  (thanks to Charles Samuels for this one)

Changes since 0.2 include:
- alternating colors in listview
- Configurable keyboard-shortcuts
- Drag and drop menu (as seen in konqueror and konsole)
- work more document-oriented, i.e. FlexPlaylist works like any other app
  that opens and closes documents
- Added right-click context menu for playlist items
- FIX: If player is stopped, deleting current item started playing next item
