Removed duplicate custom controls calls in callouts.
Fixed style of a callout-styled field inside a callout dialog when it's the first field.
Changed the field styling to be based on class for callout resources instead of ID so that we don't use #callout_resources twice if we want to style sub-content in a second dialog.
Moved the OB/Session/SQL above inclusion of the nav tree in the admin in case a custom nav tree wants DB access.
Added a check for login in case it's a generic non-module ajax.
