Applying Patch for Issue 1317: support for Unicode (m3u8 Winamp)

I have cleaned up the patch previously attached to URL posted below and attached one myself there:
https://code.google.com/p/ps3mediaserver/issues/detail?id=1317

- All the import statements (of the original attachment) are already present in the latest 1.90.2 snapshot as it is, so cleaned them up...
- The remainder of the patch is unchanged...
- I have compiled a repository here myself
- I tested it on a PS3 and it works fine now for the UTF-8 (unicode) m3u8 to be played with PMS

I have implemented this patch in a Fork of the PMS project...
This is my first tryout at GitHub to share something, so bare with me if I have done something wrong in the sharing process.
Hope you can now tick off Issue 1317 as fixed/implemented :+1:
