Advanced and General in towers

Previously, spellcasters and General type units added additional bonuses to towers beyond the standard units.  These bonuses are now only occuring for the hero.  I haven't brought this up before because I thought it was intentional.  If this was covered in the changelogs please forgive me.  Those things are quite massive as of late due to the fantastic improvements you guys make to a game from my childhood that remains relevant to this day because of your efforts!
