* set default volume to 1.0 in Gigasampler engine (was 0.0)
* implemented "SET CHANNEL AUDIO_OUTPUT_CHANNEL" LSCP command
* fixed "GET ENGINE INFO" LSCP command
* fixed "GET CHANNEL INFO" LSCP command
* src/network/lscp.y: fixed 'stringval' rule (returned string with formal
  apostrophes), fixed 'dotnum' rule (ignored position after decimal point)
