2.13 (non-recurring) all day events with showEnd show wrong date. Oct 11, 23:59 instead of Oct 12, 23:59

[sdetweil]

US holidays shows Columbus day ending on the 11th, instead of 12th.
end date not adjusted to end of day for full day single events..

start is Oct 12, 00:00:00, end is set the same, then 1 second subtracted oops..
