* added and implemented a set of 19 new LSCP commands for controlling
  internal effects:
  - added LSCP command "GET AVAILABLE_EFFECTS"
  - added LSCP command "LIST AVAILABLE_EFFECTS"
  - added LSCP command "GET EFFECT INFO <effect-index>"
  - added LSCP command "CREATE EFFECT_INSTANCE <effect-index>"
  - added LSCP command
    "CREATE EFFECT_INSTANCE <effect-system> <module> <effect-name>"
  - added LSCP command "DESTROY EFFECT_INSTANCE <effect-instance>"
  - added LSCP command "GET EFFECT_INSTANCES"
  - added LSCP command "LIST EFFECT_INSTANCES"
  - added LSCP command "GET EFFECT_INSTANCE INFO <effect-instance>"
  - added LSCP command "GET EFFECT_INSTANCE_INPUT_CONTROL INFO
    <effect-instance> <input-control>"
  - added LSCP command "SET EFFECT_INSTANCE_INPUT_CONTROL <effect-instance>
    <input-control> <value>"
  - added LSCP command "GET MASTER_EFFECT_CHAINS <audio-device>"
  - added LSCP command "LIST MASTER_EFFECT_CHAINS <audio-device>"
  - added LSCP command "ADD MASTER_EFFECT_CHAIN <audio-device>"
  - added LSCP command
    "REMOVE MASTER_EFFECT_CHAIN <audio-device> <effect-chain>"
  - added LSCP command
    "GET MASTER_EFFECT_CHAIN INFO <audio-device> <effect-chain>"
  - added LSCP command "APPEND MASTER_EFFECT_CHAIN EFFECT <audio-device>
    <effect-chain> <effect-instance>"
  - added LSCP command "INSERT MASTER_EFFECT_CHAIN EFFECT <audio-device>
    <effect-chain> <effect-instance> <effect-chain-pos>"
  - added LSCP command "REMOVE MASTER_EFFECT_CHAIN EFFECT <audio-device>
    <effect-chain> <effect-instance>"
* bumped version to 1.0.0.cvs7
