CHUI-283: Now the avatar icon loads in the user's avatar image.Also the avatar image is of proper size. The participant of the conversation is offset correctly as well.

CHUI-283: Now upon the information icon and speaker icon do not overlap the username text. Instead the username text will be truncated with an ellipse to prevent the overlap. Also did a code cleanup.

CHUI-283: Basic Implementation, just have hard coded avatar icon appearing and profile/info buttons visible. profile/info buttons do not have proper positioning or mouseclick events.

Removed AT_ROOT_CATEGORY and FT_ROOT_CATEGORY since those types are unused.  Changed FT_CATEGORY to FT_ROOT_INVENTORY to make its purpose more clear.

This change assumes that no agent inventories have category type 9 for either inventory type or folder preferred type.
