=================================
* fixed the getEventDisplays method for day.py to use the
getOccurrencesInDay method since it already does the work for us
and it passes in the request.form so we can modify the search.
[claytron]
* fixed the calendar_view_tabs macro so that the id gets the proper
title from the action, thus validating the page.
[claytron]
* made the menu items actions (day, month, week, list, past) keep
what we had in the request
[lucielejard]
* when we get the occurrences in a day, made the day end at 11:59pm
instead of 12am the next day. This was causing events starting at
12am to start displaying the day before.
[lucielejard]
* hooked up the selection of the hour height for the day view
[lucielejard]
* hooked up the selection of how many events we want to display
on the month view and if we even want to have a limit
[lucielejard]
* hooked up the selection of "start hour" and "end hour"
(site setup -> chronos configuration) with the day and week views.
[lucielejard]
* updated the display of events that last more than one day (on day and
week views). This is possible thanks to the variable column_day that
allows you to know on which day you are displaying the event, and then
to know where to start/stop displaying the event on this day.
[lucielejard]
* introduced two variables, before_line and after_line, to know
if we have to display the gray lines at the top and bottom of the
day and month views. For example, if your day starts at 12am, you
don't need the grey line at the top, since there won't be any event
before 12am on this day.
[lucielejard]
* allowed to select "24" as the end time on the manage calendar
form, to be able to display hours until midnight on day and
month views.
[lucielejard]
* Fixed the _get_view_url_for_date so that it properly checks the days in the
month. http://plone.org/products/dateable/issues/7
