Subject: SL-19134 Thumbnail ctrl

LLIconCtrl stores icons indefinitely which is undesired for fairly large and expected to be numerous thumbnails, LLTextureCtrl is tied to texture picker and has a number of limitations (already processes clicks, enforces label area). Intent behind LLThumbnailCtrl is to bridge the gap - to not store texture indefinitely and to allow further customisation.
