[imp] CVS: open_compose_win.js included too early

[Chris Hastie]

Having just updated to the latest CVS I'm seeing the following warnings 
from horde/login.php:

Warning: Cannot add header information - headers already sent by (output 
started at 
/usr/local/www/mail/data/horde/imp/templates/javascript/open_compose_win.js:1) 
in /usr/local/www/mail/data/horde/templates/common-header.inc on line 3

This is with Imp included in my summary information.
