Drop Project Security Manager

Custom Security Manager used by Drop Project to sandbox students' submissions.

Current checks include:

• Calling System.exit()
• Trying to read a file outside the working dir (or one of its subdirs)
• Trying to write a file outside the working dir (or one of its subdirs)

Any of these will be detected by the Security Manager and will lead to a SecurityException being thrown.
