* Cleaned the alsa.conf syntax:

Browse source 
- added pcm.front, pcm.rear, pcm.center_lfe blocks
* Added configuration for EMU10K1 (it's fully working one!!!)
* snd_config_redirect_load->snd_config_refer_load rename
* snd_config_search_alias code change (works also with pairs base.key)
* cleanups in the evaluate function (the function prototype has been changed)
