moc 2.5.0-alpha2

Here is MOC-2.5.0-alpha2. It comes with 2 new decoder plugins, few new features and many bugs fixed. Most of the biggest changes were made by contributors (as you can see from the changelog). Unfortunately (for MOC) I have a new job in a new town and even less time to work on MOC. This is why the release is delayd and many bugs are not fixed (you can see them in the TODO file included with sources). Here is full list of changes:

• Add SID plugin using libsidplay2. (Hendrik Iben)
• Add Wavpack support. (Alexandrov Sergey)

• Add OnStop configuratipon option that allows to run an external command on Stop event.

• Fix and a possible segfault when OnSongChange option is not defined and memory allocation functions usage.
