[sugar] Choosing "defaults" for the activity ring

I personally feel that the ring view will be both a friendlier
interface, as well as a more welcoming one for kids just starting out.
 Additionally, I absolutlely want to make sure that the XO remains in
the center up front, since this is the first thing a child will see
when booting her laptop for the first time.

Additionally, I anticipate that having both starred and unstarred
activities to begin with may help make the favorites system easier to
grasp.  Empty views are often confusing.

Let me take a moment to elucidate our thought process here. (This
isn't intended as an argument, but information on how we arrived at
the current design.)  We started with the ring icon in the list, as
you suggest.  However, we then arrived at the wonderful addition of
the "recent" vs. "new" perspectives on the ring, and chose to use the
outline vs. colored icon to represent this, which seems highly
appropriate. (Refer to the Designs page on the wiki for more on this.)

For this reason, we felt it necessary to reserve the colored ring icon
instead of giving it a double meaning, and therefore reverted to the
star metaphor, which will also be used within the Journal and
hopefully elsewhere (bookmarks in Browse, for one).  Our hope is that
a few minutes of playing with this will be plenty to make the
interaction
clear, but naturally that's something we need feedback on.

The aim was to keep the XO as both the center of the ring and in the
center of the screen.  Perhaps providing a larger min radius, offering
a bit more breathing room, will be enough to offset the imbalance.
I'll try it out.

The icons do actually scale up to, if I recall correctly, 150% their
normal size in the current implementation. One thing we do need to
avoid is competing with the XO in the middle, so we want to keep the
surrounding icons at least noticeably smaller than that.  A slightly
larger radius might help here as well.

The first part is a bug, which should get fixed in short order. The
point about the activity icon is also one of internal debate in our
design team, with arguments of redundancy against the desire to a) map
directly to the keyboard and b) illustrate the conceptual 'activity
space" as distinct from any particular activity.  I would be willing
to revisit the issue, since I initially found it redundant as well.
I'm curious to hear more feedback on this one.

Indeed.  It's great to hear everyone's thoughts; thanks!
