alsactl init - CTL{values}, CTL{enums} and default "guess method" initialization

Implemented CTL{values)=value to set all values at once. Implemented CTL{enums} to match against strings in enum list. Added 'default' (guess method) initialization configuration. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
