minor bug
tighten css rules
column application dropped from `logbook`, only need to read `sessions` in uid_choiced_application() (but leave code for more general future cases)
new code for menu views, support submenus; new: moduleslist_view()
typos
relax .photo rules: also allow fake divs like <span class=block>
increase minimum year
omit group column if redundant
support for modules (wip)
