/**
 * The implementation of agent interface
 * 
 * This implementation supports agents recognized by all uix22
 * This class returns name strings (instead of int's)
 * Certain agents/platforms have been renamed
 * - using "webkit" (instead of safari), on recommendation from uix team
 * - using "gecko" for all gecko based browsers
 * - using "ppc" (instead of windows) for platform
