Nmap not found but scan still running

[rcarvalho]

When I try to perform a scan without nmap installed, an exception is outputted to log file, but the user is not being notified that nmap could not be found.

The exception is as follows:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner
   self.run()

This is a Unix-Only issue and it occurrs inside the subprocess execution. I'll create a custom thread class to try wrapping the subprocess execution to catch this exception.

When nmapCommand.command_process is None, the scan raises an Http500 error and alert the user about the error. Resolved in revision 3991.
