Changes the dialog window that pops up for any exception to tell
the user to read Python's output (i.e. the stacktrace).
Also, handles the common failure of having too small a window and
trying to create a new ncurses dialog box. There is now a specific
failure message, so people know to make their terminal bigger.
Basically, this commit removes email sending code that asked the
user for a CSC username and email to authenticate to an SMTP server
to send a mass email. Now, we just use the system utility 'sendmail'
to do it, which means you don't have to enter in your email creds
to send a mass email once you're already logged in.
