Added a check to gravatar if the libravatar addon is also enabled.
Only one of these two addons should be anabled and libravatar will fall back to gravatar if it found nothing at libravatar.
This plugin provides the default gravatar lookup feature that has been in friendica's core before.
In addition it lets you choose the default avatar image type and select the allowed image rating.
