LibKGAPI can now query FreeBusy information from Google, this adds
support for integrating with KOrganizer by implementing FreeBusyProviderBase.

Successfully tested with my Google account.

We needed Nepomuk to lookup task parent, which we now can do via GID.

Use Collection::setParentCollection() instead of deprecated Collection::setParent()

The interval (in minutes) can be configured in resource settings dialog.
The resource will then regularly check for changes and updates on the
server.

The feature is disabled by default.

...which is not supported by Akonadi.

We use calendar/tasklist UID instead of the title as collection name.
User-facing name is stored in DisplayAttribute, so the UID should
not leak to users anywhere.

Fixes 'The requested minimum modification time lies too far in the past'
error from Google Calendar resource that users saw after they returned
from vacation :-)

Also simplifies the code and speeds up sync by not fetching all existing
items before fetching data from Google (I probably copy-pasted it from
somewhere in the early days without actually understanding what's going on)

Google sends email reminders for us, so avoid duplication.

BUG: 318392
FIXED-IN: 4.11

The account provided by the resource can change while the
job is running, so in the finished() signal handler, using
resource's account is not safe. Instead we use the account
that is stored in the job and that has been used to
authenticate the request.

Fetch only events that occur after a specified date. The default
time span is three years. This filter does not take in account
recurrent events that have started before the set date (they
will be included nontheless).

GUI:

libakonadi-calendar now supports UID modification.
No longer crashes.

This kdepim-runtime branch will be merged when kdepim calendaring
branch is merged into master.

Now we are consistent with the Kolab resource
