[ZendTo] Handling of leading and trailing spaces in username

[John Thurston]

We were chasing an odd authentication failure recently and tracked it 
down to a trailing space on the username submitted to NSSDropbox.php.

I looks like the code is converting the submitted string to lower case, 
but leaving it otherwise unchanged. Is there any reason the submitted 
username shouldn't have its leading and trailing spaces trimmed? I can 
see retaining them for the password field, but I don't think I have ever 
seen a (legitimate) username with a leading or trailing space.
