Add Strong number to definition

[DavidIB]

Strong numbers are useful, so we want to show them somewhere in the def. Prob best as non-bold in top line eg In beginning: 'first' (reshit - RAShIT) H7225

If it looks OK, it would be great to have this number in smaller type than the rest. Also, it is best to use 4-digit versions, eg H0001 & G0001
