[SAC] SSL and Drupal

[Tyler Mitchell (OSGeo)]

All logins and edits are now using SSL by default and return to non- 
SSL when not needed.

I installed the Drupal "secure pages" module, that allows us to set  
what pages in Drupal should be set to use SSL.  It is nice and easy  
to configure.  The only side effect was that I had to turn off the  
login block on the front page of the site, and replace it with a link  
to the secured login screen.  We could likely modify the block's code  
but for now this was easiest.

Let me know if it causes any issues.  I've read that IE6 or other  
browsers might complain when it sees you get redirected from https - 
 >  http etc. but I haven't seen any issues like this personally.
