[Suggestion/UI] Spell Research Reminder

Several times I've found myself forgetting to check what new spells are available and thus leaving spell points at the cap without researching.  It would be handy if the game generated a little pop-up indicator (like the building complete indicators) saying "new spells are available for research", which links directly to the spells screen when clicked.  It would appear every time the spell points have crossed a threshold necessary to add additional spell choices.
