- Deleted gear button as unnecessary. There is no functionality for it.

Detached SP now has a slightly reduced height not to make it flush with the bottom bar.

* Added new icon artwork.
* Reordered the icons so that the most common ones are to the right, so that they change position as little as possible.
* Removed old 1.23 icons.

We were using a NULL pointer after checking it. Did some logic juggling to
ensure that we only use the pointer if it is non-null

Patch by Merov ported and reviewed by Tofu, from SG2.

The crash was introduced by my previous fix of this ticket in changeset 8ceebd3612f0.
The problem was that, suprisingly, even invisible (faded) toasts were destroyed when you hit Ctrl_Shift+W,
however they were still referenced by the toast pool, so the references were invalidated.

The easiest fix would be to remove all references to the toast being destroyed, no matter is it visible or not.
However, then we'd have to search for each destroyed toast in the pool, which is slow.
Besides, removing toasts from the pool compromises the whole idea of pooling (which was introduced to speed up creation of new toasts).

Another possible fix is not to destroy any nearby chat toasts when user hits Ctrl+Shift+W.
That would save us from any crashes at a price of changing existing behaviour (the toasts will remain visible).

So I went for a third option: when closing all floaters, skip invisible ones.
Then there won't be attempts to destroy invisible (pooled) toasts, so the crash won't happen,
and we don't seem to change any existing behavior.
However I'm not 100% sure of the latter statement, so the fix requires extensive testing.

STORM-159 FIXED Added sharing inventory item by dropping it on resident's Profile SP even when no IM session is started with that resident.

STORM-183 ADDITIONAL FIX Disabled the "Replace Current Outfit" option of the inventory context menu for incomplete outfits.

Bug reason: The fix of EXT-1419 disables showing nearby chat showing toasts at all whenever you close one.
That was done to prevent a crash when viewer is exiting, but closing a toast manually should be handled differently.

Fix: If a toast is being closed (destroyed) manually, just remove it from the toast pool
(to prevent further references to the invalid pointer), but keep on showing new toasts.
I've overriden LLFloater::onClose() to differentiate the two cases.

- Moved the "no session" string to XML and used it in code instead of hardcode.



- Conference string turned out to be already translated, but the way translation was happening ad-hoc chat log files on disk
would get localized names, and thus be inconsistent (and that would create problems with browsing them later).
It didn't happen already just because this string wasn't translated in other locales somewhy.
So moved localization of session name after the the creation of log file.
Also changed value of string according to Eli's comment in ticket.

STORM-156 FIXED Increased "Add Friend" button width. Disabled owerflow button resizing to get more space for other buttons.
