Don't auto-link @mentions that appear inside the context of links

This prevents illegitimate double-linking when text like
href="mailto:foo@bar.com" or <a href="http://twitter.com/bar">@bar</a> happen
to match a BP username like @bar.

Introduce $args param to BP_Groups_Group constructor and groups_get_group()

This argument array can contain the following toggles:
- update_meta_cache (pre-fetch all group metadata for the queried group)
- populate_extras (pre-fetch last activity, admin/mod lists, and current user
  access/membership status in queried group)

Both items default to false, for backward compatibility

Allowing these pre-fetch toggles to be set to false allows us to avoid large
numbers of unnecessary database queries in certain cases, such as when
secondary avatars are populated on activity directories.

Don't prime activitymeta cache in BP_Activity_Activity::construct()

bp_activity_get_meta() now uses the core API functions. get_metadata() works by
priming the cache with *all* object metadata when requesting any piece of
metadata for that object. This means that, instead of pre-fetching activitymeta
when instantiating BP_Activity_Activity, we wait until it happens in
get_metadata(). At best, this can help us to avoid pre-fetching a meta cache
that will not be used.

Install default options at installation time and at upgrade to 2.0

When BuddyPress is installed, all basic config options should be saved to the
database, even when the setting is empty (0). This ensures that the options
will be pre-fetched by the first call to wp_load_alloptions() and stored in the
non-persistent cache, removing the necessity to make additional failed queries
to the wp_options table.

This changeset also includes logic to add missing default options to existing
default installations when upgrading to 2.0.
