Lots of changes to jinamp

Hello everybody

Yes, it's another round of jinamp (working on it is a good way of not doing what I should be). A lot of the work is internal but the big user change is that you can now create a config file to specify the player, rather than having to do it at compile time or specifying on the command line every time.

I've also run this one though a few machines on the SF compile farm, so it definitely compiles on BSD and even Solaris systems (and Solaris is so braindead that tar doesn't accept the -z flag). There are still a lot of #if/#endif's missing from the code but it looks reasonably happy on POSIX systems (which is all it's ever likely to run on, considering the features it requires).

Finally, I've also done some more tweaking to the playaudio script so that it should even handle filenames starting with a -. I'm not sure if my previous round of changes made it into the release, so if playaudio has been giving you trouble, try the latest version.
Hope it works for you all.
