* Modifications by Andreas <php  chr(64) simply  chr(46) nu>
* + Added more options to slimp3()
* + Added playlist() /w related options
* + Modified display() to get strings with spaces instead of +'s provided by urlencode
* + Modified _parse() to handle new options. Quick'n'dirty hack, could probably be prettier!
*
* Updated by Vollmer (vollmer@ampache.org)
* + Added timeout on fsockopen and error information
* + Added comments and cleaned up code to fix ampache coding standards
