* remove <report> and <act_window> form the backend tutorial
* remove documentation for <report> in the report doc
Also various fixes and improvements:
* add ACL to the wizard in the tutorial, as transients now require ACLs
* fix indentation & spacing in rST
* reword a few bits
* improve styling of footnote references (and recompile stylesheet
with recent lessc which apparently changes its output formatting
quite a bit)
