major Full Grid updates: AutoEpisodeAdvance, getCurIndexFromFullGrid
 * AutoEpisodeAdvance re-coding - more efficient and works with full grid
 * current index from fullgrid was wrong due to header row/row items
 * new logic to reload full grid when items are "not supported" and watched(remove)
   I.E. watch the last episode in a season from the "unwatched" full grid
        item was removed, but other rows were not reloaded, which is needed
        to shift items in each row due to removal (or possible addition)
