STORM-730 FIXED Made Movement Controls, Camera Controls and Nearby Voice floaters use active floater transparency.

STORM-690 ADDITIONAL FIX Hide "Loading..." text that can be seen under transparent Avatar Picks accordion.

By the way, fixed losing focus when switching between panels in Me and Places SP (which made the floater semi-transparent).

* Normally toasts are as opaque as specified by "inactive floater opacity" setting.
* When mouse is hovering a toast, the toast uses "active floater opacity" setting.
* Fading toasts have 1/2 of "inactive floater opacity".

Metrics were crediting inactive regions (those not current but
contributing to the sample) with additional time at the end of
the sample interval.  Corrected.

Cleaned up some of the messaging code that sends the LLSD stats
report off to the viewer.  Added WARNS-level messages when there's
a problem with delivery that will result in a data break.  Users
probably won't care.  Added an outbound data throttle that limits
stats to the 10 regions of longest occupancy.  Should be a
reasonable first cut.

STORM-579 FIXED SLURLs color for residents and objects names in plain text chat match the user setting for "URLs" in the Color tab in Prefs.
Avatar names SLURLs now use the user color setting for "URLs" everywhere across the viewer.

The TextureFetch thread was still stalling out due to
a different path that determines whether there is work
or not in the thread (uses getPending()) and that had
to be harmonized with the changes to runCondition().
I'm not happy with this solution but a refactor of the
LLThread tree isn't in the cards right now.

Besides, removed redundant space before colon.
