Performance improvements for the nearby media floater when lots of media is present.

Added LLViewerMediaImpl::mInNearbyMediaList for LLFloaterNearbyMedia::refreshList() to use to keep track of which elements it's seen -- this allows us to remove a linear search in an inner loop.

Added a map from texture ID to media impl pointer in LLViewerMedia/LLViewerMediaImpl.  This allows LLViewerMedia::getMediaImplFromTextureID() to be a std::map lookup instead of a linear search.

In LLFloaterNearbyMedia, call sortByColumnIndex in postBuild instead of in addMediaItem().  The latter was causing some unnecessary re-sorting.
