git bash windows compatibility (#249), fixes #248

* removed 'rev' command from build script for Git Bash for Windows compatibility as rev is not a native bash command on that platform.
* Substituted `pwd | rev | cut -d'/' -f1 | rev` for $(basename $("pwd")) but also could have used `pwd | sed 's#.*/##'` for the same effect

* Same rev command fix applied to clean.sh
