NEW Basic escriptize support

* make escriptize
* ./smother
* Compiling code with 'TEST' macro for easier integration with rebarized projects
* preprocess option currently unsupported in escript (couldn't make it work)
* smother escript would benefit from cleaner file management in smother: compiled code been dropped
  at /tmp, no option to generate reports in a specific location, etc
