[SM-PLUGINS]Quicksave plugin fix

[Doug A. <Dou...@ho...>]

Greetings,

I'm running SquirrelMail 1.2-rc1.  I downloaded the Quick Save plugin, and
it does the trick nicely, except in IE 6.0, it generates a Javascript error.
The script is attempting to read the length attribute of a non-existent form
element, which raises a Javascript error.  Simply adding a conditional to
check for the existence of the form element *before* checking that element's
length solves this problem.

I've updated the Quick Save setup.php file on my system; how do I resubmit
this back into the codebase?  If at all?  I have been unable to locate an
email address for the author of this plugin (Ray Black III).  Forgive my
ignorance; I'm new to open source projects.

Thanks.
