MDL-39190 Javascript: Pop-up calendar days of week wrong

The YUI2 calendar widget (still used via 2in3) uses midnight as the time
component of its Date objects, which triggers a Safari bug resulting in
11pm Saturday being returned instead of midnight Sunday when subtracting
days to get the last few days of the previous month.  This shows up ONLY
on the month after DST begins, if DST begins on the last Sunday of a given
month (and the Calendar widget is set to Sunday as the first day of the
week).  The fix/workaround of using noon instead of midnight is employed
by YUI3 and others.

MDL-47069 admin: Add option to upload required ZIP at the check page

The plugins check page displays other plugins that the current one
depends on.  Previously, we always displayed the other plugin as a link
to the plugins directory. This did not work well in two scenarios:

* The admin wants/needs to upload the other plugin from the ZIP file
  (e.g. it is not available in the plugins directory),

* the other plugin is actually a standard plugin that is not supposed to
  be registered with the plugins directory.

This patch displays the Install or Upload or Check for updates links
next to the required plugin instead, as appropriate.
