Prompt for Password

[prestonmcgowan]

In several environments it is against the security policy for a password to be saved in cleartext.

I would suggest a method for Roxy to prompt the user for the password. Also, when invoking recordloader and other child processes, the password should not be passed in where a "ps -ef" will show the password.
