Summary:  Send class in /phpgwapi/inc/class.send.inc.php fails if sent a large 
file.

I do not use the email app, but I am quite certain it is not the mail server I 
use, since I can use other email clients and send very large files.  I am not 
using apache2, so I don't think that is the problem. Since I am able to get the 
larger attachments sent when changing the php.ini memory and max timeout...it 
leads me to believe that it is phpgw and not my server.  



Just for debugging purposes, I noticed that when sending the 1MB file it went 
through the 'do' loop 17,151 times!!!  I'm pretty sure that is why things are 
timing out or using to much memory.  



P.s. just a quick look at the email app, and I see that it does not seem to use 
the same 'send' class as the calendar app.
