more name hint interace updates
- add long card name to device description - create empty PCM plugin to allow right hint description parsing - reorder devices in alsa.conf - make namehint more configurable (using default.namehint.showall switch) - add two levels basic and exteded for hints to default configuration files - do not show direct device aliases - removed all known memory leaks
