Issue #2376917 by jdwfly, guschilds: Use Google Calendar API v3 to construct Calendar address (v2 is deprecated)

the "numbering" method of handling multiple blocks is not ideal - it should be named so that blocks can be
added/removed individually, regardless of where they fall numerically.

currently used)

bug fix (workaround) for PHP/SimplePie leaking memory
bug fix for google xml not giving correct results sortorder=ascenting
was needed.
2500 events are no longer downloaded and pared down - it only requests
as many events as num_events. If you have multiple interleaved
calendars, this means num_events * N, where N is the number of
calendars, but it will take only the first num_events events.

feature addition: "day groupings". You can now enable groupings of "Today", "Tomorrow", "This Week", "This Month" and "Other"

TODO: configurable dates?

but no differentiation is made between different calendars.

fix this before it becomes an issue

(http://drupal.org/user/75278)

I added:
 - per-block support for "no events" and "footer" text.
 - checkbox in admin panel to disable the "new style" templating (in case somebody doesn't want to have their events in an unordered list tag (perhaps they are using tables?)
 - added gcal_events.css, a user css page that is included if it exists. Note that a theme CSS file WILL override anything in this .css file, as the theme file is included last

By default, this new templating system is enabled, but it can be disabled with a checkbox to revert to the old style

bug details: all-day events have no timezone associated, so when you
request a date range, the all-day events overlap differently than
normal events. This hack checks all day events to make sure the day is
correct, throwing out the ones that are not.

minor fix to "today only" function - works for most things, but all-day events are still not working properly. Possible bug
in google docs API

added support for "today only" block setting.

cleaned up xm address code to use an array of settings with a join rather than a messy string.

 - Cache Duration was being set to "0" in all cases. Added "Cache Duration" configuration option.
 - Fixed bug introducted with "reset block defaults" feature.
 - Fixed name of reset blcok defaults function

Features:
 - Cache Duration configuration
 - Cleaned up debug mode outputs
 - Timing information added to debug mode

Minor:
 - Added to description in admin page for calendar ID and private ID

feature: ability to enter the XML address for Calendar ID and Private ID and have just the ID be parsed out of it.

scripts

uses google calendar XML feeds as a source. SimplePie is required to parse the XML
feeds.
