Upgrade gmusicbrowser to upstream version 1.0.1

Binary package hint: gmusicbrowser

Version 1.0.1 is out upstream.

I intend to package it.

Here's the changelog (mostly fixes and a few new features, nothing too fancy):

v1.0.1
- Fixed bug when writing flac tags with non-ascii characters with perl 5.10, that could damage the file
- Fixed searching for artist pictures on last.fm
- Fixed replaygain tags not written correctly (only one of the 5 fields was written, and with the locale's decimal separator, rather than ".")
- use Net::DBus::GLib when available rather the hack to connect Net::DBus to the Glib mainloop
- Fixed some resizing problems with the FB container
- Renamed the mozembed plugin to webcontext, it can now use either Gtk2::MozEmbed or Gtk2::WebKit
- added -add command-line option to add files/folders to the library
- added -playlist, -enqueue, -addplaylist, and -insertplaylist command-line options
- updated translations : spanish (jjgomera), polish (tizzilzol team)
- added an oxygen icon theme (Zeltak & pete)
