[contactsd] Add Telepathy StorageInfo to CDTpAccount

This interface is used to get the provider name for the account, and
potentially other information in the future.
[contactsd] Set AccountDisplayName and ServiceProviderDisplayName on contacts
[contactsd] Update contact account display names when changed
[contactsd] Delay sync of CDTpAccount until extra info is available

Sync calls for a CDTpAccount (whether newly created or on startup) are
delayed until an extrainfo request completes, so that account/provider
names are available.

[contactsd] Store account and provider display names on contacts
[contactsd] Allow disabling transient SIM contact import.

This commit now changes the behaviour of the sim plugin depending
on the value of a configuration value.  If the value is "1"
then the sim plugin will transiently import sim contacts into
the phone addressbook automatically, otherwise it will not.
The default value assumed for the setting if it does not exist
is "1".

[contactsd] Only process aggregate contacts' birthdays

Other contact types are not relevant to birthday processing.
[contactsd-birthday-plugin] Disallow modifying and creating event to birthday calendar by calendar application.

Merge pull request #54 from matthewvogt/aggregate-contacts-only

[contactsd] Only process aggregate contacts' birthdays
[contactsd] Set only start time for birthdays

Setting end time with addDays(1) is wrong: with all day true the end time
is considered inclusive, thus it would be two day event.
Avoid by not setting end time, such should be considered one day event.
