Patch that touches 'upstream' templates, for use in surveys.
Consists out of three changes.
1 - Move the </head> placement in base.hmtl to after the closing of
scripts_block, so templates that extend base.html can add scripts to
the <head>.
2 - Add tooltips for checkboxes inside fieldsets.
3 - Comment out an empty table row in templatetags/_as_table.html,
which probably has an arcane reason to stay empty :)
