* Fix locking issues in services discovery
* Add playlist_Replace function
* Beginning of playlist_TreeMove
* Fix some warnings
* Doxygen update

  - basic data retrieval implemented
  - data display not yet implemented
  - many broken outlets and even more broken actions
  - won't compile
  - if you work on this (and please do) please communicate this fact to the IRC channel and make regurlar commits to prevent that multiple people work on this (and especially the NIB).

Coding style fixes (much more left)

  fix the playlist autodelete
  

 * all lines where first non white space char is a # is a comment

don't forget to add options to  *ppsz_sout_options[] (so that ca, crt, etc.. are also available using http{ca=...,crt=...} in the sout chain...

s8,16,f32,u8,16,f32 and little endian).

 * net: support for SOCKS proxy support (for all TCP connections).

 * network: export ipv4 name resolution.

   This gives better results when moving the window, but resizing is still
   flickering

* src/audio_output/input.c: made the resampling just a bit quicker (trying to reach a good compromise).
