Set up subscription to update@status.net for admin user on new installation, if OStatus is set up and working. (Will fail gracefully on a behind-the-firewall site.)

* 'testing' of gitorious.org:statusnet/mainline:
  some more editorial on README
  Increased admin navigation width to handle longer text length

from CSS instead.

Dropping the earlier PubSubHubbub plugin; OStatus plugin is taking that portion over (with both internal and external hub options for user and group feeds).
Todo: add support for other feeds to OStatus PuSH hub implementation.

Bad lookup was sending us to the first group instead of the selected group.

Ignore API 'since' silently as Twitter does instead of throwing a 403 error. Getting extra results is less disruptive than total failure.
Threw in an X-StatusNet-Warning header on the off chance some API client developer notices it. :)

Added partial data conversions:
user_groups -> local_user: ids, names filled out; mainpage, uri left null
notice -> conversation: stub entry added to push the autoincrement past existing notice items
