survey-devel-list: error logging

hi all,
   sorry for the cross posting on both survey-discussion and 
survey-devel lists, I hope this won't be a big problem.

I worked on a new future during the last days.

I've implemented a solution that permit to handle errors without (I 
hope) scarring users ;)

As you know, when an error occurred (e.g a syntax error or an error 
related to db connection or... so on) a scarry red message was displayed 
to the user that can do nothing to resolve it.

I change this and now the user recieve a quiter message that inform 
him/her that an error occurs.

On the other side the survey's creator can choose to receive an e-mail 
whenever an error occurs but anyway errors are always logged to a file 
specified in survey.conf.

On survey developing time you can set SHOWERRORS SURVEY property to yes 
to view all error messages as before.

I tested this changes a bit but more test is needed. I find very 
comfortable with these new features.

Summarizing:
  - there's a new SURVEY property called SHOWERRORS that's default
    setted to no; you must turn it on (setting it to yes) to be
    able to see error messages on your web browser as they appeared
    before my changes.
  - there's another new SURVEY property called (by now... new name can
    be choosen) MAIL_ADMIN which is the mail address to send error email
    to.
  - there's two new env that can be setted in survey.conf:
     _SURVEY_ALERT_MAIL that must be setted if you want to receive email
     on error. (email will be sent to MAIL_ADMIN SURVEY's property or to
     _SURVEY_MAIL_ADMIN otherwise).
     _SURVEY_LOG_FILE which is the path to the log file.

I don't change the installer to take care about the new survey.conf 
settings so by now you've to adjust it by your-self.

Technically speaking I've defined an ErrorHandling sub on each .pm file 
on Survey dir (only that level not in sub-level such as Component). This 
is not soo good. I'll think about it trying to find a nicer solution.

Anyone interest in testing this feature can use the code in mod_survey 
devel cvs tree:

Stay tuned,
bugant.
