update to support thinking_sphinx v3

One additional change would be that there would need to be a ts_searchd file in /engineyard/bin/searchd something like this:

```
#!/bin/sh
# This script starts and stops the searchd
# This script belongs in /engineyard/bin/searchd

export PATH=/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2
###############################################################################

usage() {
  echo "Usage: $0 <appname> {start, stop, configure, reindex} [environment]"
  exit 1
}

if [ $# -lt 2 ]; then usage; fi

if [ -z "$3" ]; then
  FRAMEWORK_ENV=production
else
  FRAMEWORK_ENV="$3"
fi

if [ -d /data/$1/current ]; then

  cd /data/$1/current

  if [ ! -f $CONFIGFILE ]; then
          echo "$CONFIGFILE doesn't exist! Exiting" >> $OUTPUT 2>&1
  fi

  # handle the second param, don't start if already existing
