Setting tag plewww-4.3-49
bugfix in slice page, had wrong (null) expiration date
upgraded to raphael-1.5.2, don't minimize this lib
nicer layout for password fields as well
long tag values in the slice page (ssh keys..) get truncated, plain value show on hovering
marginally optimized slice page (2 GetNodes call down)
minimal profiling cap., and usable in the slice page with _GET[profiling]=1
_GET[resa_slots] to set number of slots, _GET[resa_offset] to book in the future (in hours)
reservations can cope with a bit more slots - will need scrolling someday
omf text has hyperlinks to the tools
