[Soot-list] Soot bootstrap helper shell script

[Wei Peng]

Another bugfix. "free" defaults to kilobytes. So the last line should be:

[ -f ${THE_JAR} ] && java ${JVM_OPTS-$(free | awk '($7) {printf "-Xmx%d*k*",
$7/2}')} -jar ${THE_JAR} "$@"

i.e., there is a "k" after %d.

GitHub version is updated.
```sh
wget https://raw.githubusercontent.com/pw4ever/dev-env/master/bin/soot -O
$HOME/soot && chmod +x $HOME/soot
```
