Three main changes:

- Now the sample is executed using a predefined user and its associated environment. To define that user and its associated environment, you need to run gb_configure.py as that user. That way, gb_configure.py will save the environment from that user to grassbox.conf

- Naive approach to process tracing selection. Right now, only process whose PID is greater or equal than the sample PID (new processes) are traced. Code injection, scripting... = fail

- Opened files blacklist implemented (right now, just to avoid /dev/dtracehelper to be listed)

File changes:

- gb_binary_launcher: Sample executed with a predefined user
- gb_configure: Read current user environment and saves it to grassbox.conf
- gb_report: Opened files blacklist implemented
