Bug 11618: ensure jQuery timepicker is picked up by the i18n toolchain

We handle internationalization of the jQuery datepicker by adding
language configuration strings to calendar.inc which can be processed by
the translation script. This patch adds a similar configuration file for
the timepicker.

This patch also upgrades the timepicker plugin to the latest version,
minified, and places it outside the prog template directory for global
use. The path in templates has been updated accordingly.

CSS has been added to more completely hide the controls for seconds,
milliseconds, and microseconds.

To test, apply the patch and clear your cache so that the browser
loads the new version of the jQuery plugin. Confirm that date and time
selection still function correctly on the circulation page, the patron
detail page, and the offline circulation page (circ/offline.pl).

Test at least one datepicker instance which does not use the
timepicker.

Run translate update on a po file and confirm that the timepicker
strings are now present.
